"For decades, strong bilateral relations have fueled and reinforced significant U.S.-Israel cooperation in many areas, including regional security. Nonetheless, at various points throughout the relationship, U.S. and Israeli policies have diverged on some important issues. Significant differences regarding regional issues-notably Iran and the Palestinians-arose or intensified during the Obama Administration. Since President Donald Trump's inauguration, he and Israeli Prime Minister Binyamin Netanyahu have discussed ways 'to advance and strengthen the U.S.-Israel special relationship, and security and stability in the Middle East.' Since late 2016, a number of developments involving President Trump, the Obama Administration, Israeli leaders, and various other actors (including Members of Congress) have affected U.S. policy."
