U.S. Pentagon Launches Six-Month Review of European Force Posture

On July 27, Pentagon policy chief Elbridge Colby announced a six-month review of U.S. forces in Europe, dubbed “NATO 3.0.” The review will produce at least four option packages for Defense Secretary Pete Hegseth by November 6, with a final decision expected in December. It follows recent troop adjustments, including the 2025 withdrawal of a 3,000-person unit from Romania and a brief, reversed plan to send 5,000 troops to Poland.

The effort aligns with the administration’s shift toward the Indo-Pacific and its push for NATO allies to assume greater conventional-defence responsibility. The Pentagon has circulated a questionnaire to NATO members probing public support for U.S. policy, weapons purchases, and basing rights.

• About 80,000 U.S. military personnel remain in Europe, roughly half in Germany.

• A congressional provision sets a floor of 76,000 troops, allowing reductions only after Pentagon-Congress consultations.

Foreign Policy

• Prior actions: 3,000 troops withdrawn from Romania (Oct 2025); a planned 5,000-troop deployment to Poland was cancelled in May 2026 and briefly reinstated.

• The review will assess troop numbers, locations, timing of changes, and financial impacts.

Colby said the Pentagon has already received several questionnaire responses and will review them. Secretary of State Marco Rubio signaled support for maintaining a stronger U.S. presence, while NATO Secretary-General Mark Rutte noted progress on European defence spending but warned that “much more to be done.”

Roger Wicker and Rep. Mike Rogers criticized the October Romania withdrawal. NATO officials expressed skepticism that the review is a genuine consultation, suggesting Washington may have already decided on substantial cuts.

Analysts differ on the likely magnitude of changes. Pentagon insiders have hinted at “significant reductions” in forces, aircraft, and warships if NATO were attacked, leaving the final impact uncertain.

• “We're actually having a kind of down-to-business conversation about how we go forward together in a world in which Europe, which is obviously a very wealthy continent, can and is taking primary responsibility for its own conventional defence,” — Elbridge Colby

• “I think in the naval domain, you’re unlikely to see any major changes,” — Jennifer Kavanagh, Defense Priorities

Foreign Policy

• “These reviews are always a lot of hype, and then the changes are always less than what we expect,” — Jennifer Kavanagh

A decision briefing between the top U.S. general in Europe and Colby is scheduled for September 18. By November 6, at least four option packages will be delivered to Hegseth, after which a December deadline will mark the formal conclusion of the review. European allies continue to submit questionnaire responses, and further diplomatic engagements are planned at NATO headquarters in Brussels.
