I'm not sure to the extent you can blame the USA for this. I'm an amateur at history, it's just a hobby. Probably somebody like 2cents could answer it more accurately, as all I'd give is 'feels' - 'Somewhat' is my feeling, but both Israel and Palestinians have missed many opportunities too.
Nah if you made me supreme Jewking [no antisemitism here, promise] my first proclamation would be, 'right lads, we're off. Do you fancy Tanzania or Nunavut?' Perhaps a little Zanzibar in there. I'd go back and fight if it was existential of course, but if the option was fight or go to Canada... well, I like bears and prefer the cold weather.
I do know deep down it can't happen. Islamaphobia/Xenophobia runs deep, and no western nation would actually accept a severely damaged generation of Palestinians with grievances on their borders. And obviously Israel is far too cnutish to pay reparations. The irony is that I do think an Israel could thrive in most western places, and away from conflict it wouldn't give people like Bibi a chance to rise. It would have been a far better option in 1948 or whatever. But then the colonial powers never did draw borders based on what was best for the people, only what was best for their own geopolitics. Such is Israel too. It would have been interesting to see what Palestine looked like now, if it was another Syria/Lebanon, or an independent state.
I sadly agree; they'll just become refugees instead eventually, homeless and hopeless. I disagree that it's unprecedented though; Kuwait did it to many of them only a few years ago. Turks are doing it now. Don't get me started on European refugee policy in general. It's not only a disgrace, it's clearly dumb as we need the younger and cheaper workforce. It'll just be yet another sad story in the world.
ps. On casualties vs Russia (I think it was you that mentioned it) - the obvious difference is the density and scale. Russia don't have the capability to do what Israel did from the air, and to start off, for some reason Putin thought it would be easy and Ukrainians would welcome them.... We saw how that worked out. They are reverting to form and heavily using fires now (artillery), but the warfare is less asymmetric, and the huge difference is that Ukraine also has artillery, in many cases more accurate with a longer range. This gives civs a chance to get out before the Russians encircle usually. Israel aren't yet using the brutality that Russia do, but what they are doing is extremely concerning. If you want a case study of Russian brutality, a better example than Ukraine is Syria, which is their weapon testing ground. That said, Israel have [probably] already killed more kids in Gaza in a month than Russia managed in 8 years. So grim either way.
