“Complex” doesn’t mean “balanced”. Israel has always pulled underhanded shit like extending its de facto borders by means of “settlements”. The Hamas/PLO fight also didn’t happen without its involvement. But there have also been factors like the involvement of foreign powers, German guilt, the similarity between Zionism and early Nazi deportation plans, and so on.
The conflict between Israel and Palestine has been a mess from the very beginning and it’s understandable that people were reluctant to get involved. Of course these days most of that complexity doesn’t matter and not taking a stand is a luxury we shouldn’t be able to afford.
(I’m saying “shouldn’t be able to” because honestly we routinely ignore genocides; this one just happens to be particularly hard to ignore because Israel is a spotlight hog with huge diplomatic influence.)
Except it’s not for all. They get all of the downsides but few of the upsides.
It’s like they’re paying for something, not receiving what they paid for, and being told they don’t want what they’re paying for in the first place. Expect they’re also wildly overpaying.
