Why is Israel accused of occupying gaza and West Bank . They were attacked 6 times and won a those wars and got that land in part of the agreement in ending the wars . So that is Israel land since they won the war .
Gaza is under Hamas, although I don't know if Israel still has siege around it.
West bank Israeli occupation is illegal by international standards. After the 6 day war in 67 odd, The International community revised the earlier border of 47 (where Israel had lesser land area) & divided the area in a way such that only Gaza & West Bank was for Palestine & the rest was for Israel.
So any Israeli settlement of West Bank is illegal as the international community recognizes that land as a future Palestine state (PLO is an observer kind of thing in UN). This idea that you can fight in wars & annex & that part becomes yours is medieval. Any country can annex any part then. The West Bank is the last hope for a future Palestine state.
West Bank is still largely composed of Palestine people - Do you kill millions of Palestine people similar to the Holocaust because there is no way these people can live within Israel & neither will everyone abandon their homeland & flee (many millions have already fled as refugees anyways). This conflict will only blow up. We had 2 Intifadas, we are just sitting on the cusp of a 3rd more horrible one.
This is a Vox video about about the basics of the Israel-Palestine conflict - But it is sad how moderate Israeli leaders have also been murdered by their own people

Illegal by international standards lol what they won the land in 1973 in a war they didn't start which means it's their land period .
