How old does something needs to be for it to be bullshit. Because the land palestinians have lost is now pretty old too, and their claim is subsequently bullshit. They should just accept that Israel exists, it won various wars, and now owns a lot of land where palestinians used to live.
And regarding the "ownership" Israel has over the land, well... when your 300-million-strong neighbors around you all hate the digestive bacteria in your guts and your army is the same thing as your people, I wouldn't exactly call that a stable or a secure way of living. In fact, that just sounds like a good old apartheid regime to me, not really surprising though given that Israel is just a European colony who powered through decolonization through sheer dumb luck and a powerful nanny/benefactor/ally state.
But when the world have thrown out the jews from their homes in all the neighboring countries and collected them in Israel at the same time Palestinian Arabs were thrown out from their homes in what is today Israel it becomes weird to talk about only one of those events in isolation, don't you think?
Just because Israel integrated their people instead of putting them in camps waiting for the others to be "showeled out into the sea" doesn't mean they are worse?
IIRC (I'm not that into India / Pakistan) this was about the same thing UN tried when they divided India / Pakistan aroubd the same time.
