It would all be over if Hamas lays down its arms.

Like the Nazis did.

Of course, Israel could call a halt too.

Like the Allies didn't do in 1944.

Any government's first responsibility is to defend and protect its citizens. That's what Israel is doing and Hamas is not, regardless of politics. Hamas is pledged literally to wipe Israel off the map and replace it with a Muslim theocracy. Israel is not sworn to wipe Gaza off the map or to kill Palestinians. Israel withdrew its troops and settlements from Gaza in 2006. Hamas has been in charge since then.

Are both sides "equally to blame" for the current situation?
