This bill aims to prevent unauthorized military action against Cuba by establishing a temporary prohibition on the use of federal funds. It specifically bans the obligation or expenditure of any appropriated funds for military force in or against the Republic of Cuba, effective from its enactment until December 31, 2026. The legislation outlines specific conditions under which this prohibition would not apply. Funds may be used if Congress declares war on Cuba or if it enacts specific statutory authorization for such military force after the bill's passage, provided this authorization meets the requirements of the War Powers Resolution. Additionally, the prohibition does not apply to uses of military force consistent with section 2(c) of the War Powers Resolution, which describes the introduction of U.S. Armed Forces into hostilities. This measure seeks to reinforce congressional oversight on the deployment and funding of military force.
