Occupation of Iran in World War 2

If the German attack on the looming danger to their north did not go without pleasure on the part of the Iranians, I would be very surprised, and indeed, there was some public rejoicing.  However, the soviet relivation of a German spy network in Iran caused immediate concern, and both the British and the USSR delivered warnings of a possible pro-German coup in Iran.  Therefore, the allies demanded the removal of Germans, including vital technical specialists, from Iran.  Further, the British conceived the idea of a joint invasion with the USSR as supporting player.
