The answers to this conflict are not in the history. I don’t care who came first, the chicken or the egg. Besides, if you dig deep enough, the oldest artifacts and recorded history in the entire region are Judiac.
Hamas is in charge of Gaza. The thing preventing Gaza from having what it needs is Hamas. They can’t follow zero international laws and norms whatsoever and expect to be treated like a legitimate state actor. They are not. Hamas is a terrorist organization and the present hostilities will not end until Hamas is gone. Hopefully they stop taking innocent people with them.
