Again, this is an essential distinction. States are not peoples. A national group is the people of a state, not the state itself.
The axis states ceased to exist after world war II. Despite gratuitous bombing by allied forces, the peoples of the states continue to exist, and largely inhabit the same territory.
Seemingly by your argument, land can be seized, people expelled, war crimes committed, but if you have created a state, it would be inherently wrong to dislodge you. I personally don’t regard states as a magic blanket that rules out decolonization by definition.
Now it seems we’ve reached a “verbal argument” where it’s just an argument over definitions, which I’m not interested in.
This is where I’m personally going to leave this:
Some people see the 70 -year genocide of the Palestinians as an unspeakable atrocity that plainly justifies violent and non-violent resistance.
Some people want to center the fears of the occupiers in the discussion, and use that to throw up their hands and shut down any action or solution that isn’t on the occupiers’ terms.
