Believe it or not i can condemn a country’s actions and think they lost the right to exist in their current form without thinking that the people living there should be displaced, or that everyone living there is in full support of what’s going on.

Similar to how you might notice that germans still live in germany, but the governmental structure was transformed and there were (poor and insufficient) attempts at denazification. (And yes, plenty of germans were displaced. In similar situations as current israelis would be. But there’s a difference between going to another part of your country and having to go far away/into a neighbouring country. Some suffering is unavoidable once you start a war, and innocents that were powerless to stop it will be swept up in it even on the attacking side)

Ideally I’d say have palestine govern the area and let the israelis live there, but realistically that can only go wrong since there will be a very understandable grudge that isn’t going away for a long time.

Regardless, if you genocide your neighbour (or anyone), you lost legitimacy as a country in my eyes.
