Who is Reza Pahlavi, the son of Iran's last shah?

Reza Pahlavi, the 65-year-old exiled son of Iran's last shah, has emerged as a leading voice urging continued protests against the current Iranian regime. These protests, occurring throughout Iran, have reportedly resulted in approximately 2,500 deaths according to human rights groups, as the government attempts to suppress the demonstrations. The US, under President Trump, has not dismissed potential military intervention in response to the violent crackdown. Pahlavi's role is significant as questions arise about his level of support within Iran amidst the ongoing unrest. He is advocating for change in Iran from exile.
