Definitely sad, but that is what you get when you fight wars the western way. That is the way of losers.
In order to win a war, you have to defeat the enemy military and civilians. You do that by killing them until they publicly admit defeat and give up. If they won't give up, then keep killing them. You may have to kill most or all of the civilians population if they won't give up.
That, of course, is genocide and a war crime, but it is the only way to win. Note that the last time America won a war was when it nuked Japan. Currently, the western way of war means never winning another war again.
Getting back to Israel, no Palestinians means no problems. Depopulate Gaza and the West Bank by killing everybody and driving off the rest.
Before you blame me, this is the scenario in Isaiah 17. Apparently, Israel is going to nuke all of its neighbors. Of course, this puts into the play WW3. Note that this Isaiah 17 scenario appears to be at Israel's doorstep right now.
