The injustice and illegality of Israel's settlement building is apparent even to Donald Trump. 

The reality is that in relative terms, only a very small number of Jewish religious extremists are standing in the way of a peaceful resolution to this decades old conflict. However, these extremists and their political cronies hold great sway in the Israeli government. And they viciously attack any suggestion that Israel doesn't have a God-given right to the West Bank. Standby for Trump to be called anti-Semitic.
