re: Why do so many Americans feel we have to always aid israel?

There are a few other variables that likely come into play as well. Eventually, in one way or another, to some degree or another. One of which being an emboldened Iran’s outlook on their nuclear program. Also a very possible implication would be the net effect on this apparent “alliance” being hatched between Russia, China, Iran and to some degree North Korea as well, i.e. does that scenario add some meaningful cachet to that “axis of evil”. Just items for consideration.
