During the second term of President Barack Obama, US-Israeli relations sharply deteriorated. After a positive visit by President Obama to Israel in March 2013, major disagreements erupted over the Israeli-Palestinian peace process, over the nuclear deal with Iran and, especially, over the construction of Jewish settlements in the Israeli-occupied West Bank. Making matters worse, personal recriminations crept into the Israeli-American dialogue on the disputes. While the two countries signed a major military assistance agreement in September 2016, Israeli settlement expansion after the election of Donald Trump as the US President in November 2016 led to a further deterioration of relations between the Obama Administration and Israeli Prime Minister Binyamin Netanyahu, which was demonstrated by the Obama Administration’s failure to veto a UN Security Council Resolution condemning Israeli settlements.
