How did the imperial soldier become the commander of the army after the revolution?

Another group believes that American intelligence agencies have disclosed this information because of showing their goodwill to the Shah. The next theory considers the British or Soviet security agencies to be responsible for the leak of the coup due to the prevention of an American coup in Homeland. American published sources, while confirming that America knew about the coup plan, deny the disclosure of this information by America. The presence of a powerful opposition scared him and provoked him to carry out reforms that would prevent the fall of the Pahlavi government and the establishment of a neutral or pro-Soviet government. Finally, when the coup was revealed, he was sentenced to three years in prison.  After his release from prison, he gave up hope in America and became close to national-religious figures such as Seyyed Mahmoud Taleghani, the Freedom Movement, and Seyed Hadi Milani, which led to his arrest again.
