The United States of America has at various times in recent history provided support to terrorist and paramilitary organizations around the world. It has also provided assistance to numerous authoritarian regimes that have used state terrorism as a tool of repression.
United States support for non-state terrorists has been prominent in Latin America, the Middle-East, and Southern Africa. From 1981 to 1991, the United States provided weapons, training, and extensive financial and logistical support to the Contra rebels in Nicaragua, who used terror tactics in their fight against the Nicaraguan government. At various points the United States also provided training, arms, and funds to terrorists among the Cuban exiles, such as Orlando Bosch and Luis Posada Carriles.
Various reasons have been provided to justify such support. These include destabilizing political movements that might have aligned with the Soviet Union during the Cold War, including popular democratic and socialist movements. Such support has also formed a part of the war on drugs. Support was also geared toward ensuring a conducive environment for American corporate interests abroad, especially when these interests came under threat from democratic regimes.
On 11 April 1955 the “Kashmir Princess,” an Air India Constellation passenger airliner, was damaged in midair by a bomb explosion and crashed into the South China Sea while en route from Bombay, India, and Hong Kong to Jakarta, Indonesia. Sixteen of those on board were killed, while three survived. The explosion had been caused by a time bomb placed aboard the aircraft by a Kuomintang secret agent who was attempting to assassinate Chinese Premier Zhou Enlai, who had been scheduled to board the plane to attend the conference but had changed his travel plans at the last minute. The day after the crash, China's Foreign Ministry issued a statement that described the bombing as "a murder by the special service organizations of the United States and Chiang Kai-shek."
