Israelis and Palestinians can’t coexist peacefully while Israel exists in its current state, as an ethnostate focused on settler colonialism. That’s like saying normal people want black and whites to get along and also apartheid South Africa should still exist. They can’t at the same time, it’s fundamentally impossible. Once again, tearing down Israel as it exists doesn’t mean hurting any of the people in it (unlike what Israel is doing to the Palestinians). States are just political constructs. You could easily create a new state in that area making up Palestine and Israel called Palestine II: Electric Boogaloo with a new Constitution not based on religion and equal protection under the law, and it would be purely an improvement for everyone who lives there, and yet you’re saying that’s a bad thing?

Also, Marxism isn’t a failed political ideology. There’s plenty of states based off it that exist today. Also, capitalism has killed way more than tens of millions of people if you want to base it off every death even slightly in the orbit of a country like that (which is what those huge, ballooned figures usually do). Hell, it’s caused the destabilizing of almost every country in the global south, so I’d say it’s got an even worse track record of “failed states”. It’s only held up through imperialism, wars, and coups. For every bad thing you point at one of those countries, an equally bad event can be pointed at a capitalist country, too. Also, it’s also still a good framework for analyzing domestic policies and events as well, especially with all the enshittification happening. It’s evolved, like any science, but still extremely predictive.
