Bad article. It doesn’t present what language Trump used that led the author or other people to arrive at their conclusion.
Or what drugs the author and other people are on. (Or should be prescribed by a psychiatrist, if they aren't taking drugs.)
(I thought that Trump has a daughter who is a Jew. And grandchildren who are Jews. And his administration was responsible for the Abraham Accords. And we had 4 years of peace without any new wars. So I kinda doubt that he is encouraging another Holocaust.)
The language they are referring to is:
From the river to the sea, Palestine will be free!
Oh, wait. That wasn't Trump that said that.
