Trump is a real Xtian believer ie in addition to our Tenach, he also believes in the 2nd Coming, in the Incarnation, in the Book of Revelations, and that it is his duty to 'help' bring the Jews back to Yoshki!
Although in the USA there is meant to be separation of religion and state, Trump's deeply held Xtian beliefs are going to color his tenure in office vis a vis Israel more than any other president.
In addition, he seems to have inherited from his father a degree of Judophilia!
