Baltic Security Initiative Act

This bill authorizes $350 million annually for fiscal years 2024-2026 to establish the "Baltic Security Initiative," a U.S. defense program focused on strengthening security cooperation with Estonia, Latvia, and Lithuania (the "Baltic countries"). It requires the Secretary of Defense to develop a strategy within one year to enhance military capabilities like missile defense, cyber resilience, long-range weapons, and coordination with NATO allies - including Poland - to deter Russian aggression and address security threats from Russia and China. The initiative operates under existing U.S. defense authorities (Title 10, U.S. Code) and mandates a report to Congress detailing how these security objectives will be achieved. The bill directly affects U.S. defense funding and the security planning of the three Baltic nations.
