And of course it had utterly nothing to do with the Brits ripping off the Iranians through the Anglo-Iranian Oil Company and refusing to disclose financial records, CIA involvement in the overthrow of its elected leader, the installation of the sock-puppet Shah into power who consolidated himself into an absolute monarch, and then proceeded to trample Iranian cultural sensibilities by rapid Westernization leading to the radicalization of Iranian Islam and the revolution of 1979, and our protection of the deposed Shah leading to the hostage crisis?
