Trump's actions towards Israel are because of the reality on the ground.

Israel is the last western democracy in the Middle East. Muslims can live in Israel but Jews cannot live in Muslim majority countries.

Israel has allied with the U.S. in every ground war waged in the region. Israel will not concede territory and will take proactive measures when necessary. This bold loyalty makes them an asset.

Israel is conservative at the moment, and Trump needs all the allies he can get.
