Eastern Flank Strategic Partnership Act of 2025

The bill defines a group called "Eastern Flank strategic defense partners." These are NATO countries near Russia, Belarus, or Ukraine that meet several conditions: they must be close enough to help defend NATO’s eastern border, commit to spending 5 percent of their gross domestic product on defense by 2035 (with set shares for core NATO needs and other security uses), host or support NATO forces, and face ongoing threats from hostile states. The bill lists Bulgaria, Estonia, Finland, Hungary, Latvia, Lithuania, Poland, Romania, and Slovakia as included partners. The bill sets U.S. policy to recognize these countries as key to defending NATO’s eastern side and to treat them as priority recipients of U.S. security help. It tells the Secretary of State and Secretary of Defense, when consistent with law, to give these partners preference for certain existing programs: Foreign Military Financing grants or loans, capacity-building aid for foreign security forces under title 10, transfers of excess U.S. military equipment, and participation in military exercises, training for working together, logistics, and planning to move forces quickly. The bill also directs the Secretary of Defense to prioritize these partners within the War Reserve Stocks for Allies program, which pre-positions U.S.-owned defense articles overseas, and to consider expanding stockpiles into additional partner countries when appropriate. Finally, it requires that, within 180 days of enactment, the Secretary of Defense, with the Secretary of State, brief specific House committees on how the bill’s policies and priorities are being put into practice, including timelines, goals, and ways of cooperation.

This bill focuses U.S. defense cooperation and security assistance on NATO members that sit closest to Russia, Belarus, and Ukraine. For those countries, the bill could affect how quickly they receive U.S. military aid, training, and access to stockpiled equipment, which may change how prepared they are for potential crises. For the United States, the bill could shape how existing security assistance tools are used, without creating new programs. It ties U.S. support more closely to allied defense spending commitments and hosting of NATO forces, which may influence how those governments plan their budgets and military posture. The broader effect on regional security, NATO’s deterrence, and U.S. resources is not specified in the text and would depend on later decisions by U.S. officials and allies.

• Defines "Eastern Flank strategic defense partners" as NATO members near Russia, Belarus, or Ukraine that commit to spend 5% of GDP on defense by 2035 (3.5% for core defense and NATO targets, 1.5% for other security investments), host or support NATO deployments, and face persistent threats.
• Explicitly includes Bulgaria, Estonia, Finland, Hungary, Latvia, Lithuania, Poland, Romania, and Slovakia as Eastern Flank strategic defense partners.
• Directs U.S. policy to treat these partners as priority recipients for existing security assistance and defense cooperation authorities.
• Requires the State and Defense Departments to prioritize these partners for Foreign Military Financing, capacity-building assistance under 10 U.S.C. 333, and transfer of excess U.S. defense articles.
• Calls for giving these partners preference in bilateral and multilateral military exercises, interoperability training, logistics, and forward mobility planning.
• Instructs the Secretary of Defense to prioritize these partners in the War Reserve Stocks for Allies program and to consider expanding stockpiles into additional partner countries.
• Requires a briefing to the House Armed Services and Foreign Affairs Committees within 180 days of enactment on implementation plans, timelines, goals, and cooperation mechanisms.

• The definition of "Eastern Flank strategic defense partner" sets a future defense-spending benchmark (5% of GDP by 2035), which could affect which countries qualify over time even though a fixed list is included.
• The bill does not create new aid programs but instead reshapes how existing authorities and stockpiles are prioritized, which may change implementation without changing underlying statutes.
• The required congressional briefing covers implementation of the policy and priority sections but does not require a public report, so details might remain within Congress and the executive branch.
