I think Israel has become politically just as toxic as the USA (or moreso even). It seems incredibly unwise to make your defense industry dependent on a currently openly warmongering genocidal state.
I also think there is a huge difference between america's political toxicity, where the concern is directly about things the USA might do to the country in question vs Israel where unless you are in the middle east its more indirect concern for a third party. When times get tough, its easy to forget about third parties, you can't forget if you are the one who is the victim.
Which is probably why you see a lot of Israeli arms deals are with countries that are nervous about their neighbours. e.g. Greece just bought a 4 billion dollar missile defense system from Israel. Presumably because they are nervous about Turkey's increasingly aggressive stance.
Israeli?
edit: why was this downvoted lol, am I missing some meme about "Israelian"? That's not a word.
