The problem with Oslo is that it never got off the ground. Attacks didn't really stop and therefore concessions weren't really given. I'm not expecting you to be so grateful for Jericho. Honestly, it would be better for the Pals in my opinion to not respond to an attack where three civilians are killed. It gives the Pals sympathy points, which shouldn't be squandered killing three Israeli civilians. What does that do for the Pals? The one way that Hamas can force Israel back to the peace table is by renouncing violence and bringing in the UN and international observers to prove that it disarmed. Violence will just get them killed. Don't get me wrong, I'm not saying this would have been the case ten years ago... but it is today.
