I keep seeing this term, "False Flag," and not just from far-right nutcases.

23. The CIA planted bombs in Iran in the 1950s and blamed them on communists

But a copy of the agency's secret history of the 1953 coup has surfaced, revealing the inner workings of a plot that set the stage for the Islamic revolution in 1979, and for a generation of anti-American hatred in one of the Middle East's most powerful countries.
...
The history says agency officers orchestrating the Iran coup worked directly with royalist Iranian military officers, handpicked the prime minister's replacement, sent a stream of envoys to bolster the shah's courage, directed a campaign of bombings by Iranians posing as members of the Communist Party, and planted articles and editorial cartoons in newspapers.
...
The shah was a problem from the start. The plan called for him to stand fast as the C.I.A. stirred up popular unrest and then, as the country lurched toward chaos, to issue royal decrees dismissing Dr. Mossadegh and appointing General Zahedi prime minister.
...
In early August, the C.I.A. stepped up the pressure. Iranian operatives pretending to be Communists threatened Muslim leaders with ''savage punishment if they opposed Mossadegh,'' seeking to stir anti-Communist sentiment in the religious community.

In addition, the secret history says, the house of at least one prominent Muslim was bombed by C.I.A. agents posing as Communists. It does not say whether anyone was hurt in this attack.
...
Mr. Roosevelt (Kermit, grandson of Teddy) told the shah ''that failure to act could lead only to a Communist Iran or to a second Korea.''
