Man! That’s a can of worms!

Entire books have been written on the subject.

The U.S.and Israel have a tangled history going back most of a century at this point.

The short answer is that there are enough historical, religious, and cultural ties for the two countries to be allies long term. Since the us, and by extension NATO, needed a place of projected power in the region, and there was an opportunity to make that happen, Israel happened.

And, being real, Israel has mostly been a reliable ally since its creation as a country. It’s hard to point to a time when Israel didn’t fulfill its expected role in the relationship.

As such, it’s really no surprise that when both countries have leadership that are absolute fascist pricks, that the governments would go whole hog in supporting each other.

Again, that’s the disgustingly short, over simplified version. I don’t have enough interest to turn it into an essay, nor even a discussion, just wanted to drop my take on the matter in a simple way since I didn’t see anything in other comments to just upvote and support with a subsidiary comment as being super close to the way I would say it.
