DUBAI, United Arab Emirates (AP) — As President Donald Trump floats the idea of “regime change” in Tehran, previous U.S. attempts to remake the Middle East by force over the decades offer stark warnings about the possibility of a deepening involvement in the Iran-Israeli conflict.

The US president says "why wouldn’t there be a regime change?" after officials earlier said the strikes were aimed at ending Iran's nuclear programme.

Israel's Defense Ministry says its forces hit more Iranian government targets Monday in Tehran, including the notorious Evin Prison.
