Three U.S. Democratic senators introduced a War Powers Resolution on Wednesday to prevent military action against Cuba, as the Trump administration indicted former Cuban president Raúl Castro and deployed the USS Nimitz carrier strike group to the Caribbean. The move reflects escalating U.S. pressure on the island, with Trump declaring "we are liberating Cuba" amid rhetoric about regime change, while congressional Democrats warned against an unauthorized military invasion and cautioned that such action would lack legal authority and solid justification.
