The United Kingdom's decision to leave the European Union has ramifications beyond the UK and the EU. This article analyses the impact of the Brexit referendum on the UK's political capital in the United Nations Security Council; a dimension of Brexit that has received little attention thus far. Drawing on extensive elite interviews we show that the UK has considerable political capital in the Council, where it is seen as one of the most effective actors, but the reputational costs of Brexit are tarnishing this image. With case-studies on the UK's role in Somalia and Yemen we show how the UK has been able to further its interests with dual roles in the EU and Security Council, and the risks posed by tensions between trade and human rights after Brexit. We also analyse what it takes to be influential within the Security Council and argue that more attention should be paid to the practices of diplomacy. Influence is gained via penholding, strong diplomatic skill and a well-regarded UN permanent representative. The UK accrues political capital as a leader on the humanitarian and human rights side of the Council's agenda, but this reputation is at risk as it exits the EU.

When powerful liberal democratic states are found to be complicit in extreme violations of human rights, how do they respond and why do they respond as they do? Drawing on the example of the United Kingdom's complicity in torture since 9/11, this article demonstrates how reluctant the UK has been to permit a full reckoning with its torturous past. We demonstrate that successive UK governments engaged in various forms of denial, obfuscation and attempts to obstruct investigation and avoid accountability. The net effect of their responses has been to deny the victims redress, through adequate judicial processes, and to deny the public adequate state accountability. These responses are not simply aimed at shielding from prosecution the perpetrators and those who have oversight of them, nor preventing political embarrassment. The various forms of denial and obstruction are also designed to ensure that collusion can continue uninterrupted. A core concern of intelligence officials and ministers has been to prevent any process that would lead to a comprehensive prohibition on involvement in operations where torture and cruel, inhuman and degrading treatment are a real possibility. The door remains wide open, and deliberately so, for British involvement in torture.

Summary

• The underlying driver of the ongoing US–China trade war is a race for global technological dominance. President Trump has raised a number of issues regarding trade with China – including the US’s trade deficit with China and the naming of China as a currency manipulator. But at the heart of the ongoing tariff escalation are China’s policies and practices regarding forced technology transfer, intellectual property theft and non-market distortions.
• As China’s international influence has expanded it has always been unlikely that Beijing would continue to accept existing global standards and institutions established and widely practised by developed countries based on ‘the Washington Consensus’.
• China’s desire to be an alternative champion of technology standard-setting remains unfulfilled. Its ample innovation talent is a solid foundation in its quest for global technology supremacy but tightening controls over personal freedoms could undermine it and deter potential global partners.
• It is unclear if Chinese government interventions will achieve the technological self-sufficiency Beijing has long desired. China’s approach to macroeconomic management diverges significantly from that of the US and other real market economies, particularly in its policy towards nurturing innovation.
• Chinese actors are engaged in the globalization of technological innovation through exports and imports of high-tech goods and services; cross-border investments in technology companies and research and development (R&D) activities; cross-border R&D collaboration; and international techno-scientific research collaboration.
• While the Chinese state pushes domestic companies and research institutes to engage in the globalization of technological innovation, its interventions in the high-tech sector have caused uneasiness in the West.
• The current US response to its competition with China for technological supremacy, which leans towards decoupling, is unlikely to prove successful. The US has better chances of success if it focuses on America’s own competitiveness, works on common approaches to technology policy with like-minded partners around the globe and strengthens the international trading system.
• A technically sound screening mechanism of foreign investment can prevent normal cross-border collaboration in technological innovation from being misused by geopolitical rival superpowers.

The vote to impeach Donald Trump holds almost no surprises - on both the abuse of power and obstruction of congress articles, the votes were split entirely on party lines with nearly all the majority-led House Democrats but not a single Republican voting to impeach Trump.

However, this ‘pre-ordained’ outcome of the House impeachment inquiry does serve to highlight that the US is in the midst of a hyper-partisan political moment. Policy gridlock has led to two government shutdowns during Donald Trump’s presidency, with one further budgetary fight narrowly avoided.

With a few notable exceptions (such as USMCA), policy areas that lend themselves to bipartisanship - including infrastructure and drug pricing - have seen very little progress under divided congressional chambers. Party identification can now be overlaid with the cable news channel one watches or the newspaper one reads.

Impeachment now moves to the Senate for a trial, requiring a two-thirds majority of the Republican-led senate (or 67 senators) for a conviction. Given the congressional partisanship we are seeing, the baseline scenario continues to be that the senate will not vote to convict Trump and remove him from office - despite much being made of how many senators are likely to vote for a Senate conviction.

Why public opinion could be crucial

There is another story to keep a close eye on. The number to track is 47.2 – the current polling average of public support for Trump’s impeachment. Polling averages from the end of September 2019 (before the hearings began, but after House Speaker Nancy Pelosi announced a formal inquiry) had 49.4% supporting impeachment versus 47.2% this week.

Here’s why this number matters. If those pushing for impeachment and removal are unable to drive popular support across a critical threshold level, then those against impeachment and removal are not going to abandon the president and vote for a senate conviction. With Trump consistently polling in the low 40s on job approval, but in the high 80s/low 90s within the Republican party, this means Republican congress members concerned about re-election are extremely hesitant to distance themselves from him without a clear mandate from the domestic public. 

A tale of the two most recent presidents to face impeachment underscores this point. Gallup polling claimed 58% of adults supported impeaching and removing President Richard Nixon from office in August 1974, whereas only 35% of the public supported impeaching President Bill Clinton in December 1998, the month he was impeached.

Given the respective outcomes of those two impeachments, it suggests public support for impeachment and removal needs to increase well beyond the current 47.2%, to avoid the foregone conclusion of acquittal in the Senate (even if there are signs of the tide moving in the opposite direction with those against impeachment overtaking support for the first time in December).   

What does this mean for Democrats?

In the short term, if the Democrats want to make inroads into the hearts and minds of those across the partisan gulf, it will be critical to secure senate testimony from those in Trump’s inner circle at the time of the Ukrainian affair.

After Trump ordered individuals with first-hand knowledge of the administration’s efforts vis-à-vis Ukraine not to testify, House investigators were unable to call many witnesses with direct evidence (which in fact left the House testimony exposed to Republican claims of hearsay). With Trump impeached, more of the public is likely to tune in to the senate proceedings, and direct evidence by inner circle administration officials required to testify presents an opportunity to move public opinion.

House speaker Nancy Pelosi recognizes how crucial the procedures and participants for the senate trial will be, and has said she could delay sending the articles of impeachment to the senate as leverage for a 'fair trial'.

Democrats also have to consider how an impeachment inquiry that - at least from this vantage point - does not end in a conviction of the president plays out for the 2020 election campaign, especially if this also likely means that public opinion - and certainly Republican-party views - of Trump have not shifted.

Conventional wisdom says that foreign policy takes a backseat role in US elections. But last autumn’s Democratic primary debates suggest a potential shift is taking place in the conventional view. While healthcare dominated the discussion (Democrats attribute their 2018 midterm gains to the issue), through November foreign policy followed closely behind in second place in terms of minutes devoted to the discussion.

This trend is consistent with President Donald Trump’s America First approach to foreign policy, in which an eye is always kept on how decisions abroad play for the domestic audience. One former Trump administration official has called this dynamic the ‘recoupling’ of foreign policy with domestic policy.

The US–China trade conflict, which commanded headlines throughout 2019, is perhaps the best example of this recoupling, tying trade imbalances less with the geopolitical than with domestic impact on farmers. Immigration is another policy area in which Trump has linked domestic implications and indeed domestic opinion with foreign policy. It’s in the title: America First.

Now, for better or worse, the targeted killing of Qassem Soleimani, Iran’s response and the subsequent fallout may make US foreign policy towards Iran and the US role in the Middle East a central issue for the 2020 US elections. As it comes just ahead of the Democratic presidential primaries, voters will be looking to the candidates to differentiate their foreign policy experience and proposals for America’s Middle East policy.

To President Donald Trump, Soleimani’s assassination represents a campaign promise kept to confront Iran’s aggression.

The Trump administration initially justified the action by citing intelligence of an imminent threat to US personnel and targets, but after Defense Secretary Mark Esper called this into question, Trump tweeted that ‘it doesn’t really matter because of [Soleimani’s] horrible past’. Ultimately, Trump’s message, on the campaign trail and any general debate stage he agrees to be on, is that he has overseen a new national security strategy for Iran.

Soleimani’s removal from the Iranian calculus is just a part of this broader policy, which also includes neutralizing the Iranian government’s destabilizing influence in the Middle East, denying Iran and especially the Islamic Revolutionary Guard Corps’ access to funding for its malign activities, and rallying the international community against domestic human rights violations and unjust detentions.

To counter Trump, Democrats and democratic presidential candidates would be best-served by offering a simple argument that too links domestic interests and foreign policy: the killing of Soleimani and Trump’s national security strategy for Iran have not made the US or its interests safer.

Iran’s ballistic missile attack on US forces in Iraq, which Iran’s Supreme Leader Ayatollah Ali Khamenei called a ‘slap in the face’ for the US, makes the risks to US assets and personnel abundantly clear. Even if Iran reverts entirely to covert, proxy efforts to counter US interests, the current US–Iran tensions remain unresolved and will likely continue to persist through the 2020 elections in November.

As a matter of the first order, Soleimani was replaced by his deputy Brigadier General Esmail Ghaani within a day of the former’s death, with Khamenei saying that the Quds Force will be ‘unchanged’.

At the second order, Iraq’s parliament voted in favour of a nonbinding resolution to rescind the invitation to US forces, which led Trump to threaten sanctions and demands for reimbursement. Whether US troops will ultimately leave Iraq (following a ‘mistaken’ report that the US was preparing to depart) remains to be seen, but the destabilization of the US military presence in Iraq fulfils a key Iranian objective.

In the interim, the US-led coalition in Iraq and Syria fighting ISIS announced that it would at least temporarily cease its counterterrorism efforts to instead fortify its outposts and prepare for Iranian retaliation, opening a wider door for the resurgence of the terror group.

By arguing that the US, its troops and interest have not been made safer by Trump’s Middle East policy – from withdrawing from the Iran nuclear deal to the imposition of a ‘maximum pressure campaign’ to Soleimani’s killing – Democrats will be able to point to every post-Soleimani US injury, death, regional terrorism attack, asset compromise, cyberattack and shipping disruption as evidence.

Democratic presidential candidates also ought to be explicit about how they plan to manage tensions with Iran – strategic, diplomatic and military – particularly their position on the future of the nuclear deal.

Iran has made clear that the path to de-escalation is through sanctions relief. Asserting leverage need not always involve taking away all of your counterparty’s options (‘maximum pressure’). It also involves knowing what your adversary wants (sanctions relief) and showing a willingness to offer it (especially where it means less to you) in exchange for something of greater worth (avoiding war/a non-nuclear Iran).

Clarity around future policy of a potential Democratic president may bring de-escalation forward in a way that Trump’s statement of Iran standing down are unlikely to do.

As coronavirus spreads across the globe, states grapple to find the ideal strategy for coping with the global pandemic. And, in China, Singapore, South Korea, the US, the UK, and Europe, divergent policies are a product of state capacity and legal authority, but they also reveal competing views about the optimal role of centralized state authority, federalism, and the private sector.

Although it is too soon to know the longer-term effects, the apparent capacity of centralized state authority in China, South Korea and Singapore to respond effectively and rapidly is making headlines. In the United States, the opposite has been true. 

America’s response is being shaped by its federal structure, a dynamic private sector, and a culture of civic engagement. In the three weeks since the first US case of coronavirus was confirmed, state leaders, public health institutions, corporations, universities and churches have been at the vanguard of the nation’s effort to mitigate its spread.

Images of safety workers in hazmat suits disinfecting offices of multinational corporations and university campuses populate American Facebook pages. The contrast to the White House effort to manage the message, downplay, then rapidly escalate its estimation of the crisis is stark.

Bewildering response

For European onlookers, the absence of a clear and focused response from the White House is bewildering. By the time President Donald Trump declared a national emergency, several state emergencies had already been called, universities had shifted to online learning, and churches had begun to close.

By contrast, in Italy, France, Spain and Germany, the state has led national efforts to shutter borders and schools. In the UK, schools are largely remaining open as Prime Minister Boris Johnson has declared a strategy defined by herd immunity, which hinges on exposing resilient populations to the virus.

But America has never shared Europe’s conviction that the state must lead. The Center for Disease Control and Prevention, the leading national public health institute and a US federal agency, has attempted to set a benchmark for assessing the crisis and advising the nation. But in this instance, its response has been slowed due to faults in the initial tests it attempted to rollout. The Federal Reserve has moved early to cut interest rates and cut them again even further this week.

But states were the real first movers in America’s response and have been using their authority to declare a state of emergency independent of the declaration of a national emergency. This has allowed states to mobilize critical resources, and to pressure cities into action. After several days delay and intense public pressure, New York Governor Andrew Cuomo forced New York City Mayor Bill de Blasio to close the city’s schools.

Declarations of state emergencies by individual states have given corporations, universities and churches the freedom and legitimacy to move rapidly, and ahead of the federal government, to halt the spread in their communities.

Washington state was the first to declare a state of emergency. Amazon, one of the state’s leading employers, quickly announced a halt to all international travel and, alongside Microsoft, donated $1million to a rapid-response Seattle-based emergency funds. States have nudged their corporations to be first movers in the sector’s coronavirus response. But corporations have willingly taken up the challenge, often getting ahead of state as well as federal action.

Google moved rapidly to announce a move allowing employees to work from home after California declared a state of emergency. Facebook soon followed with an even more stringent policy, insisting employees work from home. Both companies have also met with World Health Organization (WHO) officials to talk about responses, and provided early funding for WHO’s Solidarity Response Fund set up in partnership with the UN Foundation and the Swiss Philanthropy Foundation.

America’s leading research universities, uniquely positioned with in-house public health and legal expertise, have also been driving preventive efforts. Just days after Washington declared a state of emergency, the University of Washington became the first to announce an end to classroom teaching and move courses online. A similar pattern followed at Stanford, Harvard, Princeton and Columbia - each also following the declaration of a state of emergency.

In addition, the decision by the Church of the Latter Day Saints to cancel its services worldwide followed Utah’s declaration of a state of emergency.

The gaping hole in the US response has been the national government. President Trump’s declaration of a national emergency came late, and his decision to ban travel from Europe but - at least initially - exclude the UK, created uncertainty and concern that the White House response is as much driven by politics as evidence.

This may soon change, as the House of Representatives has passed a COVID-19 response bill that the Senate will consider. These moves are vital to supporting state and private efforts to mobilize an effective response to a national and global crisis.

Need for public oversight

In the absence of greater coordination and leadership from the centre, the US response will pale in comparison to China’s dramatic moves to halt the spread. The chaos across America’s airports shows the need for public oversight. As New York State Governor Cuomo pleaded for federal government support to build new hospitals, he said: ‘I can’t do it. You can’t leave it to the states.'

When it comes to global pandemics, we may be discovering that authoritarian states can have a short-term advantage, but already Iran’s response demonstrates that this is not universally the case. Over time, the record across authoritarian states as they tackle the coronavirus will become more apparent, and it is likely to be mixed.

Open societies remain essential. Prevention requires innovation, creativity, open sharing of information, and the ability to inspire and mobilize international cooperation. The state is certainly necessary, but it is not sufficient alone.

The COVID-19 pandemic highlights the absence of US global leadership. Michèle Flournoy talks with Dr Leslie Vinjamuri about the impact of COVID-19 on US domestic priorities and foreign policy commitments.

Flournoy discusses current US strategy towards China and the Middle East and how this might change under a Democratic administration.

Global trade and the WTO – which has been at the heart of the rules-based international trade system since its creation in 1995 – faced a critical moment even before COVID-19. The Appellate Body’s demise in December 2019 led to a renewed focus on the future of the WTO. But the challenges facing the WTO run deeper than that – the organization has lost relevance as a negotiation forum, resulting in the global trade rules not having kept pace with changes in technology and the rise of China. While the WTO provides a forum for international cooperation to address the trade fallout from COVID-19, what implications will the pandemic have for the long-term reform of the global trade system?

Both the US and EU have proposed various WTO reform strategies and taken steps towards collaboration, but is a transatlantic partnership for WTO reform feasible? Do the US and EU believe that a rules-based international trade system is in their interest – especially in light of COVID-19? What are the biggest issues dividing the US and EU on reforming the WTO, and is there a common assessment of the key problems? What steps can the US and EU take to address the dispute settlement function of the WTO and to modernize the trade rules? Are there broader issues, such as environmental and social sustainability, that should be included in a transatlantic agenda for WTO reform?

In 2019, Ukraine underwent another revolution five years since the previous one – this time through the ballot box. Volodymyr Zelenskyy and his party, Servant of the People, won an overwhelming majority giving them a large mandate for change, especially for economic growth and anti-corruption reform.

Looking beyond electoral promises, Ukraine’s prime minister, Oleksiy Honcharuk, presents the plans and vision of the new government.

What are the key priorities of the new Cabinet? How will they go about delivering on the structural reforms that underpin economic growth, not least strengthening the rule of law? What is the path to steady economic growth? What are the internal and external risks en route and how can the West best assist in Ukraine’s reform agenda?

Earlier this month, US Secretary of State Mike Pompeo became the highest-ranking US official to visit Belarus since Bill Clinton in 1994. After meetings with Belarusian President Alexander Lukashenka – who Condoleezza Rice once memorably described as ‘Europe’s last dictator’ – Pompeo said he was ‘optimistic about our strengthened relationship’. 

The EU and its member states have also changed their tune, at least a little. Previously, prosecutions of democratic activists led to sanctions against the Lukashenka regime. But his less-than-liberal manner of governance did not prevent him from visiting Austria last November or from receiving invitations to Brussels. 

Eight years ago, most EU contacts with Belarusian officials were frozen. Now, Western diplomats regularly meet with Belarusian officials again. This year, a US ambassador to Belarus will be appointed after a 12-year break.

The West is also more willing to support Belarus financially. The European Bank for Reconstruction and Development invested a record-breaking $433 million in the country in 2019. The European Investment Bank only began working with the country in 2017 but already has a portfolio of $600 million.

Certain policymakers in the EU and US now, at least publicly, appear to regard Lukashenka as one of the sources of regional security and a defender of Belarusian sovereignty against Russia.

There is some truth in this. He has taken a neutral position in Russia’s conflict with Ukraine, and he has consistently resisted pressure from the Kremlin to establish a military base in Belarus.

Now, amid Moscow’s demands for deeper integration in exchange for the continuation of Russian energy subsidies, Lukashenka has shown reluctance to sell his autonomy. In a token attempt to portray sovereignty Belarus even started buying oil from Norway, although this makes no economic sense.

But Lukashenka’s long-term record shows he has done little to ensure the country’s sovereignty. Lukashenka has resisted reforms that would have strengthened the economy (because they would have weakened his own position). The political system is also dependent on Russia because Lukashenka has been unwilling to build better relations with the West. Belarusians are still strongly influenced by Russian culture and media because the authorities marginalize their own national identity.

Since the conflict in Ukraine in 2014, Lukashenka’s primary goal has not been to strengthen the sovereignty of Belarus, but to preserve his absolute control over the country.

For example, when in 2018 Russia started pressing Belarus to deepen its integration in order to retain economic support, Minsk did not reject this approach outright; instead, it discussed no less than 31 ‘road maps’ for deepening integration for more than a year, hoping to receive more benefits. For Lukashenka, greater dependency on Russia is a matter of price and conditions, not principle. 

None of this is to say Belarus has illusions about Russia. It is just that Lukashenka does not take long-term steps to protect the country’s sovereignty or to strengthen relations with the West.

Belarus needs to start economic reform with the support of the International Monetary Fund, but this cannot happen without Lukashenka’s genuine commitment to transform the economy. Absence of cross-sectoral reform has led to the deterioration of the education system as well as unprecedented emigration. Few Belarusian experts are optimistic about their country’s future. Lukashenka knows all this, but does not change his system, fearing it would damage the stability of his regime.  

The West should therefore adopt a broader policy. Lukashenka is unlikely to still be president in 10–15 years, so policymakers should develop relations with the broader ruling elite, which will remain after he leaves, and try to be present in Belarus as much as possible helping it to improve public governance and develop private businesses.

The West should also support the country’s civil society and independent media, for whom Belarusian independence is a matter of principle rather than something to be bargained away.

Lukashenka may be a strong leader, but the state he has built is weak.

Soon after assuming power in 1994, President Aliaksandr Lukashenka turned his back on democratic norms and overpowered the Belarusian political elite. However, the influence of the governing elite in Belarus is growing again. It seems likely that the current governing class could rule the country after Lukashenka leaves. It is thus important to study Belarusian elites not only to understand the current regime, but also to better forecast and navigate the political system that will one day replace it. 

This study group aims to disentangle how the Belarusian political system works, outline the types of individuals that make up the Belarusian ruling elite, assess the interaction of the elite and institutions with the West, and suggest changes that Western political actors might make to their approach to the Belarusian ruling class.

The eruption of another Icelandic volcano this week, ejecting ash plume into the atmosphere, reminds us afresh of Europe's vulnerability to 'low probability, high impact' events. Will Europe respond better this time? A forthcoming Chatham House Report shows that in such crises our governments and global businesses are in a better place to cope for a week - but no longer. This is because the full consequences of worst case scenarios are rarely factored in.

The ash cloud in 2010 is estimated to have cost the EU around $ 5-10 billion - the airlines bore about $ 1.7 billion in lost revenues and the tourism industry was hit hard. The greatest impact felt by many organisations was in human resources - the absence of stranded employees and dislocated management structures - but some companies fared better than others having learnt lessons from 9/11, SARS and other shocks to aviation. Businesses responding to a Chatham House survey on the impact of the ash cloud said that if the ash event last year had persisted just a few more days there would have been far more serious consequences.

This is not surprising given our dependence on long supply chains and the just-in-time business model. Since the earthquake and tsunami in March, for example, Japanese national infrastructure has been struggling to cope with fraying supply-chains and significantly slowed production. Carmakers and mobile phone manufacturers across the world were forced to halt or slow production as inventories of essential products - electronic components, car parts and fine chemicals - were quickly run down. Major cities for production, trade and travel are often badly affected by any international shocks, irrespective of the source, rendering the apparent resilience of having multiple suppliers meaningless.

A major scenario planning exercise conducted by Eurocontrol, five weeks ago suggests that the EU might be better prepared for an ash cloud disruption than a year ago. A key test for Europe now lies in whether member states will succeed in working together better in coordinating responses to ash threat and building public confidence in science-based risk management and planning.

Policy-makers face again the challenge of communicating a complex problem to a frustrated public. The ash cloud last year demonstrated the complication of crisis management in the media-saturated world, where opinion can be swayed by the most audible, the most active or the most politically powerful voices rather than the best informed or the most legitimate. There are important lessons here on the advantages and potential pitfalls of engaging stakeholders and the public via social and online media.

Our forthcoming report also shows a bias in the traditional media towards industry voices rather than those of the scientific community and policy-makers. During the crisis last year, there was scant public defence of the precautionary principles or safety, merely airlines duelling through the airwaves to step up pressure to remove the flight ban. First off the gate, Ryanair had already started its public relations battle last night. This time around, let's hope that traditional media will give greater airplay to voices beyond industry commentators, including scientists and experts. In-depth explanations of the science and technology involved in an event can help people assess the levels of uncertainty and risk involved in a situation, and what it means for them.

The Eyjafjallajökull ash cloud of 2010 exposed serious weaknesses in the ability of governments across Europe to prepare for an aviation crisis and implement effective responses.

One year on considerable efforts have been made to improve scientific understanding, reform the risk management approach and improve coordination at the European level. A major scenario exercise in April this year even took Grimsvötn - the volcano now erupting - as its case study. Successful management of this eruption would have five characteristics:

European countries take a consistent approach

In 2010, European countries made different decisions, based on the same scientific advice, leading to widespread confusion. This is the first test of a new set of guidelines which allows planes to fly in low and medium concentrations of ash, and puts much of the risk assessment decision-making in the hands of the airlines. Ultimately, the responsibility for aviation safety remains with individual countries. Yet a single Europe-wide system for submitting the safety assessments is not yet in place, and Eurocontrol has confirmed that some European states are not yet ready to implement the new approach - especially those who did not take part in the recent scenario exercise.

Decision-making is decisive and transparent at European level

Last time round, European-level organisations took a back seat for nearly a week. A clear structure of decision making across key bodies must emerge if public confidence in decision making is to be maintained - including Eurocontrol, the European Aviation Safety Agency and the European Commission. Coordination will be undertaken through the European Aviation Crisis Coordination Cell (EACCC), an emergency mechanism that has been activated for the first time since Eyjafjallajökull. Transparency at European level is another key test. The detailed remit and composition of the EACCC - including the level of industry participation - remains cloudy.

The aviation industry supports the best available scientific information

The accuracy of Met Office ash maps was a major point of contention between airlines and engine manufacturers on the one hand, and aviation safety regulators on the other. A new ash measuring station in Iceland (still undergoing calibration) and refinements to the modelling has reduced uncertainty, but this can never be an exact science. Tension should have been reduced by the shift of responsibility towards airlines.

Governments provide clear information to the public

Scientific and technology uncertainty is notoriously difficult to communicate, especially when it comes to articulating risks and probability. Yet this is crucial to maintain public confidence in evidence-based decision making. During the last crisis, there was scant public defence of the precautionary principles or safety.

Governments also failed to establish a clear public understanding of passengers' rights when flights are delayed. Instead the media discourse was dominated by airlines duelling through the airwaves to step up pressure to remove the flight ban. Already, it is clear that stakeholders have chosen very different media strategies to last time - notably Eurocontrol which has been lauded online for its activity on social media.

The knock-on consequences of the disruption are managed effectively

A prolonged disruption to aviation would have widespread economic and social impacts. How to manage these impacts has received much less attention over the last twelve months than the issue of when to fly in ash. If Grimsvötn erupts for longer than currently anticipated, similar challenges for cross-border transport management will emerge, followed by questions about appropriate state support for struggling businesses.
