They’re not actually. Its more like the enemy of my enemy sort of thing, thats the reason so many jews ended up in Israel in the first place because of the anti–semitism and discrimination, genocide, etc, you name it in western countries. Have you not heard about the rise of european and american nationalism in recent years. Both areas, especially europe, claim that they are at over capacity. All this rhetoric came about with the african and syrian refugee rise. The USA to this day does not have a reciprocal visa status for Israelis, they have to apply for a visa and maybe they get approved just to even transit in the USA. Such great friends are they? USA supports the war, but you will be hard pressed to find their support in other areas of basic life. The have partnership in the field of medicine as well, but Israel does a lot of the supplying in new tech and research. A lot of “american support” is rooted in evanglicalist christinanity, which means they only support israel if they stay in israel. They want all the jews to go to Israel, that is their support. How would they feel about them not in Israel? I’ve read a few accounts as how evangelicals have a mission to make jews move to israel by any means necessary even if that means making their lives hard or doing discrimination against them to get them to leave. They dont want them to be comfortable NOT in israel, nor are they so good with sharing, even amongst their own american people. The USA has one of the worst affordable and housing and homeless crisis in the world.
