I take it you have 0 knowledge of the Six Day or Yom Kippur wars? Which is how the borders in the headlines moved. I mean, heck, a lot of recent maps of Israel show in which war the territory was taken.
I kinda guessed folks were ignorant of the history but come on, this is pretty basic stuff.
I mean, Israel was taken from the Jews way back when so by your logic, aren't they just taking back their land and thus, apparently according to you, allowed to do whatever?
