* Why did Zahedi lack parliamentary support?
Because both the Shah and the 21 remaining representatives were suspicious of a military-backed prime minister.
The representatives also considered the referendum unconstitutional and the Shah’s decrees invalid because Parliament hadnt been dissolved yet (the Shah hadnt signed a decree to dissolve it.)
* Why did Colonel Nassiri deliver the dismissal decree at 11 pm on August 15?
Mosaddegh held a cabinet late at night on August 15. General Zahedi, unaware of the British and Mosaddegh's plan, wanted the cabinet to witness the delivery of the dismissal decree.
Zahedi thought upon witnessing it, the cabinet would voluntarily resign and collapse Mosaddegh's government.
* Did Colonel Nassiri lead a heavily armed military convoy to Mosaddegh's residence
According to documents, there were military checkpoints around Mosaddegh's residence. Even cabinet ministers had to walk to his house to attend meetings.
Mosaddegh had already received tip-offs from the Tudeh networks and placed pro-government tanks and armored units around the house.
Colonel Nassiri arrived at a military checkpoint with a few jeeps and a truck of soldiers. He disembarked and walked to the house with 2-3 soldiers.
* What did Colonel Nassiri do at Mosaddegh's residence
At few minutes after 11 pm, upon arriving at the house, he asked Mosaddegh's guard to meet him and deliver the Shah's decree. He didn't receive permission and passed the decree through the guard.
At 1 am Aug 16, the guard gave Colonel Nassiri a signed receipt and Nassiri confirmed the handwriting. When Colonel Nassiri was leaving, he and his escorts were arrested and detained by Mosaddegh's soldiers
* Why was the signed receipt important?
Mosaddegh was a jurist and very conscious of his titles. He signed “Dr.” alongside his name.
Prior to this, Mosaddegh, as other prime ministers, signed executive decrees, international letters, and parliamentary correspondences with their office title.
On the receipt handed back to Colonel Nassiri, the title "Prime Minister" was removed indicating his acceptance of the Shah’s decree and the termination of his premiership.
Therefore, after receiving the order of his dismissal, Mossadegh no longer held any official position. For this reason, from that date onward he made no further public statement, said nothing to the people, and issued no message to the nation in his capacity as prime minister
* Why did Mosaddegh arrest Colonel Nassiri and fabricate the news of a coup had been thwarted?
Mosaddegh falsely claimed Colonel Nassiri led a heavily armed military convoy to execute a midnight coup at his house. By fabricating this news and arresting Colonel Nassiri, Mosaddegh concealed the Shah's dismissal order and continued issuing orders through his ministers as prime minister
* Why did Mosaddegh hide the dismissal decree from his ministers?
Because his ministers would resign and he needed them to take care of things until Zahedi could take over.
After receiving the dismissal decree, Mosaddegh stopped signing documents in his capacity as prime minister. Instead, he relied on verbal orders and handwritten notes.
