in the early 1950s, agents of an Israeli terrorist cell operating in Egypt planted bombs in several buildings, including U.S. diplomatic facilities, then left behind "evidence" implicating the Arabs as the culprits (one of the bombs detonated prematurely, allowing the Egyptians to identify the bombers). Israel's Defense Minister was brought down by the scandal, along with the entire Israeli government.
The Russian KGB apparently conducted a wave of bombings in Russia in order to justify war against Chechnya and put Vladimir Putin into power (see also this essay and this report). And the Turkish government has been caught bombing its own and blaming it on a rebel group in order to justify a crackdown on that group. Muslim governments also play this game. For example, the well-respected former Indonesian president claimed that their government had a role in the Bali bombings.
In his new exposé of the National Security Agency entitled Body of Secrets, author James Bamford highlights a set of proposals on Cuba by the Joint Chiefs of Staff codenamed OPERATION NORTHWOODS. This document, titled “Justification for U.S. Military Intervention in Cuba” was provided by the JCS to Secretary of Defense Robert McNamara on March 13, 1962, as the key component of Northwoods. Written in response to a request from the Chief of the Cuba Project, Col. Edward Lansdale, the Top Secret memorandum describes U.S. plans to covertly engineer various pretexts that would justify a U.S. invasion of Cuba. These proposals - part of a secret anti-Castro program known as Operation Mongoose - included staging the assassinations of Cubans living in the United States, developing a fake “Communist Cuban terror campaign in the Miami area, in other Florida cities and even in Washington,” including “sink[ing] a boatload of Cuban refugees (real or simulated),” faking a Cuban airforce attack on a civilian jetliner, and concocting a “Remember the Maine” incident by blowing up a U.S. ship in Cuban waters and then blaming the incident on Cuban sabotage. Bamford himself writes that Operation Northwoods “may be the most corrupt plan ever created by the U.S. government.”
