Will he comeback alive?
American and Israelis are friends and Israel is one of the secure state for now on security. Trump be in Israel are one thing that has not been happening with American president for quite some time now. And we should commend him for that.
Unless Mossad know something the public doesn't and want to get rid of him. Either way if they do they'd do it in the US or while he's on a visit to some other country. Maybe make it look like he was killed by terrorists.
