After Saturday's major attack on Iran by the U.S. and Israel, U.S. President Donald Trump has called on the Iranian public to “seize control of your destiny” and rise up against the Islamic leadership that has ruled the nation since 1979. After assassinating several top Iranian military officials and nuclear scientists, Israeli Prime Minister Benjamin Netanyahu has warned that Iran’s Supreme Leader Ali Khamenei could be next, saying that could topple Tehran’s entire leadership. However, there has been no immediate information on whether any top Iranian officials were killed in Saturday's attack. And even if Iran’s top leaders are killed, regime change is not guaranteed.
