Part of the post-World War II tactics of the United States included supporting assassination attempts against foreign leaders with Fidel Castro leading the way:
In fact, Cuban intelligence estimated there were precisely 638 attempts on his life – many backed by the US.
The bearded leader is said to have survived exploding cigars, exploding seashells, a poisonous fountain pen and even a mafia-style execution…
“If surviving assassination attempts were an Olympic event, I would win the gold medal,” he would later joke.
But, Castro wasn’t the only one. The Church Committee of the mid-1970s revealed a number of attempts on foreign leaders (from Wikipedia):
Among the matters investigated were attempts to assassinate foreign leaders, including Patrice Lumumba of the Democratic Republic of the Congo, Rafael Trujillo of the Dominican Republic, the Diem brothers of Vietnam, Gen. René Schneider of Chile and Director of Central Intelligence Allen Welsh Dulles‘s plan (approved by President Dwight D. Eisenhower) to use the Sicilian Mafia to kill Fidel Castro of Cuba.
Under recommendations and pressure by this committee, President Gerald Ford issued Executive Order 11905 (ultimately replaced in 1981 by President Reagan‘s Executive Order 12333) to ban U.S. sanctioned assassinations of foreign leaders.
Together, the Church Committee’s reports have been said to constitute the most extensive review of intelligence activities ever made available to the public. Much of the contents were classified, but over 50,000 pages were declassified under the President John F. Kennedy Assassination Records Collection Act of 1992.
Despite all the talk of the United States acting as the world’s policeman (and this presumes police act in the public’s best interest), the United States has a sordid past of foreign involvement. It is not just a recent thing. The drone strikes of today can be seen as descendants of these earlier activities. And the legality of it all is still questionable: we are not often officially at war with some of these other nations (at least there has not been an official declaration from Congress) though the activities are said to be against “enemy combatants.”
