Buying a house is legal, but annexing and building on occupied territory is illegal according to international law.

if you frame it that way, no, but if you take into account the open terrorism of irguin, the murders and ethnic cleansing of the nakba, 80 years of apartheid and casual killing, and the genocide since 2023, its all crimes for 80 years. So try again with the framing of the problem.

Found the zionist! You need to read up on the history of Palestine, rather than echo israeli hasbara.

Try 'A Very Short History of the Israel-Palestine Conflict' by Ilan Pappe to start 🙂.

Unless a Palestinian tries to do it, of course.
