I think Trump is a psychopath. He is bent on destroying the peace in the Middle East.
I wouldn't pretend to know whether Trump himself is aware of it or not, but the people controlling him plan for the current inhabitants of Israel to become "burnt offerings 2.0"
'Holocaust' references 'burnt offerings' for those who don't know. Some Jews needed to be sacrificed to get statehood for Israel. The Zionists and the Nazis worked under the 'transfer agreement' to evacuate the rich and healthy ones to the promised land. A certain number of poor, old, sick, and ignorant ones actually did meet their end as 'burnt offerings' in the camps in Europe which worked out well for the Zionist and their new state.
The next phase is the destruction of Israel, a total war which will demoralize the entire world and make then accepting of the promise of 'peace'. Then the coming of a 'descendant of David' who, along with the newly formed Sanhedrin, will rule from a to-be-constructed third temple in Jerusalem.*
I know it sounds crazy, but after listening to a lot of presentations by a lot of the more radical of the rabbis, I'm pretty confident that a depressingly large number of people believe this, and believe it strongly enough to look forward to it and to try to make it happen. Unfortunately some of these freaks have a great deal of power. These includes the Chabad-Lubavitch followers Jared and Ivanka Kushner. Perhaps 'The Donald' as well, but it doesn't matter because he's clearly playing ball fully with them at this point.

(*) This is Ver-I which is the one sold to the Jewish faithful. Ver-II is attributed to Pike and it is that the new ruler who is presented will be in actually a Masonic/Kabbalahist/Luciferian type from their stable. For my part I'm not sure that there is much difference.
