Yes that will happen. And he will have help from an unknown source, who will quickly take over the world. He is the man known as Ali Khamel Mohsen, who was allegedly killed by an Israeli Air strike, which was probably not Israeli responsibility.
This world leader will die with Trump, for good, after a period of exactly seven years from the signing of the new agreement on the Whitehouse Lawn. This agreement will involve the Jewish Temple, protections for Jewish people etc., but the world leader will break the covenant, take over the new Temple, sit on a big throne he will have set up there, and call himself God, demanding complete obedience from people everywhere. War will happen in a constant chain which will shake all the powers that be, but at the same time there will be alot of good things happening, but they will be hidden at first.
