As for removing invaders in general, when talking about nations, not private land... Then my stance is exactly the same as palestine. The people born ont he land have a right to citizenship of the land they are born to. Historic claims mean nothing to me beyond what you were entitled to at birth (so if your dad owned the land when you were born to it, or he was born to it as well you have a claim, but not to anyone who owned land before your birth).
