Last March, the tumultuous relationship between Benjamin Netanyahu and Barack Obama reached a new low. Over White House objections, the Israeli Prime Minister tripped to Washington to attack the President’s signature foreign policy legacy, the Iran nuclear deal. FRONTLINE traces the stormy history of the United States-Israeli relationship through the eyes of Obama and Netanyahu, two men with fundamentally different views of the world. For Obama, his election in 2009 provided a chance “to recast the United States as a friend of the Islamic world,” says White House insider Sandy Berger. But, for Netanyahu, Obama’s vision of the Middle East threatened Israel’s existence. Told through riveting footage and interviews with political insiders in Jerusalem and Washington, Netanyahu at War provides the essential context needed to understand the ongoing feud between Netanyahu and Obama and how it could shape the future of the Middle East.
