Barack Obama, 1961-

The 44th U.S. president, Obama was less active in seeking Middle East peace than his three immediate predecessors and tried to strengthen relations with Israel’s neighbors. He split with Israeli Prime Minister Benjamin Netanyahu over the 2015 Iran nuclear deal, and the United States abstained on the anti-Israel U.N. Security Council Resolution 2334 in December 2016. But national security cooperation remained strong, and Obama approved military aid totaling $38 billion over 10 years in 2016.
