You could get rid of both Biden and Trump, whoever replaced them would be beholden to the same imperial corporate interests and be just as vile with their policies.
You could do Putin or Zelenskyy in, and another capitalist oligarch would just take their places.
If Netanyahu disappeared tomorrow, Israel has plenty of genocidal politicians ready to fill his boots.
The real world isn’t a Marvel movie, there is no single “ultimate bad guy” to rally against. The entire systems of these places need to be overcome.
I don’t think this is entirely fair, it depends on your definition of “substantial”.
Israel like anywhere is a country with people with a range of opinions. A large percentage dislike Bibi, and there certainly will be a number of Israeli people who are anti-genocide, you can see their parliament has a wide range of parties in it. Doesn’t justify any of Isntrael’s actions.
“Substantial” has clearly not been enough to amount to any perceivable resistance to an occuring crime against humanity. Israel is a very small, very new settler colony; it’s residents who are not Palestinian have far less of an excuse to be there and simply “checked out” than those in other settler colonies.
