台湾海峡危機
When the Communist Party of China's forces seized control of Inchaing Island, located 210 miles north of Taiwan in mid-January 1955, calls for U.S. military intervention intensified as the CPC's continued attacks towards Quemoy and Matsu, extending armed skirmishes between the two governments as far as mainland Chinese ports. These developments prompted action from President Eisenhower. On January 24, Eisenhower requested permission from Congress to use military force to defend Taiwan. By the next day, January 25, 1955, the House approved a resolution requested by President Eisenhower that authorized the president to defend Formosa (Taiwan) and the Pescadores Islands by a vote of 410-3 in the House of Representatives. On January 28, 1955, the Senate approved the resolution. On the same day the U.S. Senate approved this resolution, the Formosa problem had finally gained the attention of the U.N. Security Council. However, due to the PRC's refusal to join the discussion, the issue was effectively dropped from the agenda of the U.N. Regardless, with the approval of the House and the Senate, President Eisenhower moved forward by signing the Resolution on January 29, 1955. The U.S. officially adopted the Formosa Resolution, a purported mechanism to prevent another crisis in the Taiwan Strait, as was experienced in the First Taiwan Strait Crisis (1954–1955). The Resolution empowered President Eisenhower to fully defend Formosa by granting him the authority to employ U.S. armed forces in the Taiwan Strait. While the Resolution authorized the U.S. president to use force to defend Formosa, it did not explicitly express an overt support for the ROC's government. The Resolution was an attempt to prevent further military conflict between the People’s Republic of China and the Republic of China without explicitly siding with Formosa.
