Trump's Middle East policy heavily favored Israel, moving the U.S. Embassy to Jerusalem and introducing the Israel-centric "Deal of the Century." He withdrew from Obama's Iran nuclear deal, imposing severe sanctions and assassinating Qasem Soleimani. Biden sought to return to the Iran deal but faced Congressional opposition and failed to renegotiate. His approach differs from Trump's, focusing less on Israel and Saudi Arabia. Biden is preparing a significant aid package for Israel, including support for the Iron Dome, amidst pressure from Congress and the recent Hamas attack.
