Ah, yes. In the U.S. we had Operation Northwoods, where not one of those psychopathic "leaders" who concocted it was disposed of, either expediently or forcefully:

http://en.wikipedia.org/wiki/Operation_Northwoods DoD proposal that "called for the Central Intelligence Agency (CIA), or other operatives, to commit acts of terrorism in US cities and elsewhere... public support for a war against Cuba by blaming it for terrorist acts..."

Also see "Gulf of Tonkin incident." Any others?
