According to Charles Kurzman (1996), what perception motivated Iranian protesters who toppled the shah's regime in the late 1970s?

According to Kurzman, the perception that motivated the Iranian protestors to topple the Shah's regime came from the strong and sudden belief that they could win.

Explanation:

The developments that led to the overthrowing of the Shah of Iran by the citizens had begun with the growing affinity between the Shah and the then president of the United States. As the citizens that were protesting realized that they had vast support and the Shah had already began to fear their actions, their confidence multiplied and their belief that they could win became rigid.
