During the Islamic revolution of 1979, the U.S. embassy was actually the second major Western "landmark" that was sacked and occupied during the uprising. A special honor as a scholar in modern Iranian history goes to the Freeper who knows which building was first.
Congratulations - you have invented the factless lesson.
US Embassy in Islamabad, Pakistan.
Double honors to you if you can cite a source in English that even posits a connection between the elimination of the two regional American “listening posts” and the Soviet invasion of Afghanistan immediately thereafter.
