Coalition Senate floor alert in opposition to California SB-1081

The California Senate will vote this week on a bill to automatically register register draft-age applicants for driver’s licenses and state IDs with the Selective Service System for a possible future military draft.

The floor vote in the state Senate on SB-1081 is expected this week and could come at any time.

[Update: The Senate voted 23-2 in favor of SB-1081, with 15 Senators not voting. The Senate approved minor amendments to the bill by its author, which make the bill somewhat worse. The bill now goes to the state Assembly Committee on Transportation, where it is scheduled for a hearing on Monday, 1 July 2024. See this letter to the Assembly Transportation Committee in opposition to the current version of SB-1081.]

SB-1081 was held in the 'suspense' file by the Senate Appropriations Committee, but was called up and sent to the floor for a vote by the full state Senate despite both Democratic and Republican opposing votes in committee, with only minor amendments that fail to assuage any of the opponents of the bill.

As amended, SB-1081 is still opposed by a diverse coalition including the ACLU, the California Immigrant Policy Center, Asian Americans Advancing Justice, and the Military Law Task Force of the National Lawyers Guild.

Yesterday, during markup of the National Defense Authorization Act (NDAA) for Fiscal Year 2025, the U.S. House Armed Services Committee approved an amendment to the NDAA that would automatically register all draft-aged male U.S. residents with the Selective Service System for a possible military draft, based on information from other Federal databases.

This system of automatic draft registration would replace the system in effect since 1980 in which young men can decide for themselves whether or not to sign up for the draft -- and so many choose not to register that the Selective Service database would be useless for an actual draft.

[Excerpt from the summary released by the Senate Armed Services Committee of the version of the NDAA for FY 2025 approved by the SASC and to be voted on by the full Senate.]

A proposal to expand registration for a possible military draft to young women as well as young men is moving forward again this year in Congress, along with a seductively simple-seeming but in practice unfeasible proposal to switch from the current system in which young men are required to register with the Selective Service System (SSS) to a system in which the SSS tries to identify and locate everyone eligible for a future draft and automatically register them based on other existing Federal databases from the Social Security Administration, IRS, U.S. Citizenship and Immigration Services, etc.

Today both the U.S. Senate Armed Service Committee and the full U.S. House of Representatives approved different proposals to expand and/or make it harder to avoid the requirement for men ages 18-26 to register with the Selective Service System for a possible military draft.

The proposals for changes to Selective Service registration were approved during consideration of the Senate and House versions of the National Defense Authorization Act for Fiscal Year 2025, a "must-pass" annual bill that typically runs to more than a thousand pages.

The Senate Armed Services Committee (SASC) approved a version of the NDAA that would expand Selective Service registration to include young women as well as young men. This version of the NDAA will now go to the floor as the starting point for consideration and approval by the full Senate.

Also today the full House of Representatives approved a different version of the NDAA that would make Selective Service registration automatic while keeping it for men only.

A House amendment proposed by Rep. Warren Davidson (R-OH), a West Point graduate and Army veteran, which would have replaced the provision to make draft registration automatic with a provision to repeal the Military Selective Service Act, was not "made in order" by the Rules Committee to be considered or voted on by the full House. There was no separate House floor vote on the proposed change to Selective Service registration, only a single vote on the entirety of the NDAA as a package.

The SASC markup was conducted in closed session, and only a summary of highlights of the version adopted by the SASC was released. It's not clear whether the SASC version also includes the provision in the House version of the NDAA to try to make Selective Service registration 'automatic' or only the provision to expand the registration requirement (with which compliance is currently low) to young women as well as young men. A spokesperson for the SASC told The Hill today that the full text of the Senate version of the NDAA won't be released until sometime in July.

Floor amendments are still possible in the Senate before it approves its version of the NDAA. But as of now, it seems likely that competing bad proposals with respect to expansion and/or attempted enforcement through automation of Selective Service -- one from the Republican-majority House to try to make it automatic, and one from the Democratic-majority Senate to expand it to women -- will be included in the House and Senate versions of the NDAA and go to the eventual House-Senate conference committee to sort out in closed-door negotiations late this year, after the elections.

It's possible that either or both of these proposals were included as "bargaining chips" intended to be withdrawn in exchange for concessions on other issues during the conference negotiations. The conference committee could include either, neither, both, or some other compromise on Selective Service in its final package of compromises, which typically are voted on and approved "en bloc" without further amendments.

Either of these misguided proposals would be the most significant change to the Military Selective Service Act since 1980. There have been no hearings, debate, or recorded vote on either of these proposals, and there appear unlikely to be any. The decision will probably be made in secret by the House-Senate conference committee for the NDAA.

[“I have an amendment at the desk.” Rep. Chrissy Houlahan introduces a proposal from the Selective Service System to automate draft registration in the House Armed Services Committee, May 22, 2024.]

Under fire for proposing an ill-considered amendment to this year’s National Defense Authorization Act (NDAA) to “automatically” register all young men in the U.S. for a possible military draft, Rep. Chrissy Houlahan (D-PA) has issued a statement that casts more doubt on her understanding of the current draft law and on the wisdom of her proposed changes to Selective Service registration.

Rep. Houlahan starts by claiming that “This new legislation saves taxpayers significant money.” But there’s absolutely no evidence to support this claim.

[Originally published by Responsible Statecraft, the journal of the Quincy Institute]

Two proposals that would radically alter the current system for registering Americans for a future draft were introduced recently in Congress without any hearings or debate.

They raise practical issues about whether any draft today would even be possible.

As part of this year’s National Defense Authorization Act, the House voted this month to make registration with the Selective Service System of all draft-eligible men ages 18-26 “automatic.” In addition, the version of the NDAA on its way to the Senate floor would expand draft registration to include young women now, too.

Debate about the draft has typically been framed around whether the U.S. “needs'' a draft. Debate about women and the draft has been framed around whether women “should” be required to register. But the bigger question we face is three fold: will women sign up voluntarily (if in fact registration is not “automatic”), is “automatic” registration based on other databases feasible, and can registration or a draft – for men and/or women -- even be enforced.

When I was invited to testify before the National Commission on Military, National, and Public Service (NCMNPS) in 2019, I told them that “any proposal that includes a compulsory element is a naïve fantasy unless it includes a credible enforcement plan and budget.... Women will be more likely to resist being forced into the military than men have been, and more people will support them in their resistance.”

Contrary to earlier reports, the U.S. Senate has joined the House of Representatives in moving toward a foolhardy attempt to 'automatically' register all draft-eligible U.S. citizens and residents for a possible military draft, by extracting and aggregating information obtained from other Federal agencies.

The proposal for "automatic" draft registration is among several previously-undisclosed provisions related to Selective Service in the newly-release version of the National Defense [sic] Authorization Act (NDAA) for Fiscal Year 2025 approved by the Senate Armed Services Committee (SASC) and to be considered by the full Senate.

The 1,197-page SASC proposal for this year's NDAA was approved by the committee in closed session last month, and only a summary was released. At the time, a spokesperson for the SASC told me that if "automatic" Selective Service registration had been included in the bill, it would have been included in the summary. That proves to have been incorrect: The proposal for "automatic" draft registration was included in the SASC version of the bill, but not in the summary.

Fantasies underlying push for conscription are delusional and dangerous.

Doubling down on their recent war-game exercises and report on the (un)readiness of the U.S. to activate a military draft, Taren Sylvester and Katherine Kuzminski of the Center for a New American Security (CNAS) have a new article in War on the Rocks, “Preparing for the Possibility of a Draft Without Panic,” laying out why they think the U.S. needs to prepare for a draft in order to be able to win an all-out war with China over Taiwan.

CNAS and War on the Rocks like to describe themselves as “realists”. But their arguments for stepped-up planning and preparation for a draft are strikingly unrealistic, in at least four respects:
