This joint resolution establishes official U.S. policy to refuse recognition of Russia's territorial claims over Ukraine and reaffirms American support for Ukraine's sovereignty and independence within its 1991 internationally recognized borders. The bill specifically names five Ukrainian regions—Crimea, Donetsk, Luhansk, Zaporizhzhia, and Kherson—that Russia has illegally occupied or annexed, and declares that the United States will not recognize any Russian claims over these territories or take any actions implying such recognition. The resolution is grounded in the international legal principle that unlawful acts cannot create legal rights, even through force or the passage of time, and references the historical Welles Declaration of 1940 as precedent for rejecting territorial seizures obtained through aggression. The bill has no direct funding or implementation timeline but serves as a formal statement of U.S. foreign policy affecting relations with Russia and support for Ukraine. It was introduced in March 2025 by a bipartisan group of House members and referred to the Committee on Foreign Affairs.
