I think lots of thinkers of his time had bad stances on Isreal though.

I mean its a fairly consistent view on utopian socialists (anarchists included), its social imperialism.

Kibbutz are the wet dream of utopian socialists, small self-organized enclaves built on stolen land and, of course, subsidized, what’s not to like for the average western leftist! The genocide and displacement of the indigenous peopoe is handled by others so you get to feel morally good too.
