Obama is well aware that a lot of his legacy rests on what happens just before he leaves office, especially with both presidential candidates being incredibly unpopular, so he’s looking to try one last time to wrap up a lot of the problems and diplomatic conflicts that still divide the world.
Netanyahu and Obama have had differences of opinion on multiple issues, including the Iran nuclear deal, so tensions have been strained between the two leaders at times. But the recent passage of a $38 billion package in aid for Israel is meant to show that despite past clashes in opinion, the US will continue to support Israel.
So we’ll see what Obama has up his sleeve for the Israeli-Palestinian conflict soon, but it’s almost certainly not going to be enough. This dispute has been going on for over 50 years at this point.
