It has now been persuasively argued -- as shown, for example, in this History Channel video -- that Nazis set fire to their own government building and blamed that fire on others (if you have trouble playing the clip, it is because the website hosting the clip requires you to download the clip before playing it). The fire was the event which justified Hitler's seizure of power and suspension of liberties. And 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. See also this confirmation. And the Russian KGB apparently conducted a wave of bombings in Russia in order to justify war against Chechnya and put Vladimir Putin into power. The Turkish government has carried out bombings and blamed it on the PKK in order to justify a crackdown on that group.This is called "false flag terrorism", where a government attacks its own people then blames others in order to justify its goals. But NOT the U.S.
