I don't share your enthusiasm. What's Israel going to do? Start bombing the Palestinians and occupy their territory? Wait--
Let's say Hamas sponsors a terrorist attack in Tel Aviv. What happens next? Carpet bombing Gaza? Like that region could be anymore of a hell-hole than it is now? Like it will make the Palestinians stop attacking Israel? The only other answer is to re-occupy their land - woops! It's no longer disputed territory, it's Palestinian territory. It's an invasion. Now Syria and Iran can claim that Israel has invaded a sovereign territory and start the war in earnest as "allies" of Palestine. Regardless of who was the initial aggressor, Israel is going to be blamed throughout the world and the invading bully. This is a no-win situation for Israel.
The only "good" thing here is that it's probably considerably sped up the timetable for this mess to come to a head.
I understand the thought that this puts Hamas squarely on notice, but so the hell what? They've been "on notice" for a decade now. Anyway we can cut this, it sucks for Israel.
You just can't be more completely wrong! It gives Israel a perfect, justfied reason to stop making any pretense of going through a PHONY/SHAM peace process. THAT IS A BIG WIN!
When Israel occupied it the first time, it was Jordanian and Egyptian territory.
