Are you ignoring the fact that Israel was attacked by multiple armies multiple times ?Is that like shack coming over and saying he had to steal your home because you insulted him here?
Nobody has to invade and occupy any other country.
Check the map of Europe after WWII and aftermath of German invasions ....they
lost a lot of land...same applies here...Israel got attacked - attackers lost land, no
occupation, all according to the international law
