Imam neither compromised with Bakhtiar nor any other agent of the regime and he always was after overthrowing the monarchs. His purpose was to initiate a revolution and didn't accept to take any steps back or even to stop for a little while.
He believed that when a system is against Islam, its culture, its army, its economy and its politics, it must be changed, and power must be transferred to an Islamic system.
