We didn't take over land from them, force them out as refugees and then say that they have no citizenship in the lands in which they once lived.
Israelis assert a right of return based on what legal claim? If they do assert this right of return (which is not based on former physical occupancy by an individual) then their claiming former occupants have no right of return based on prior legal ownership and physical occupancy (legal refugees) is specious.
A thief just can't pick your pocket and then say the wallet is his simply because now he happens to be holding it in his hand.
And the illustrative example most apt would be Native Americans whose lands were stolen and reparations paid (subsequently) and yes despite being sovereign internal nations (occupied), they have US citizenship and rights.
Israel keeps taking land and then says that it is theirs just because they happen to be holding it in their hands.
Meanwhile no one asks Israel to make overtures for peace. Look at the state of the middle east and you have to ask is this brutal treatment of the Palestinians absolutely necessary.
Israel goads and prods and then grabs up more land for settlements and then says... but we only want peace. It is getting sickening. Wrong is wrong no matter which side does it.
