Israeli Appeasement

I've generally respected Shimon Peres. Don't agree with him too often, but he's generally always struck me as somewhat respectable. Until these comments proved him to be the worst appeaser since Neville.

I would like to know what the difference is between terror and a suicide bomber. I was always under the impression that the goal of a suicide bomber was terror. So how can the two really be separated?

I also have a big issue with the idea that making concessions to Abu Mazen now - before he has actually done anything - would be a mistake on an incredible scale. Concessions should be given only when something has been done to warrant them. Israel has given concessions in the past never with any reciprocation. Concessions only bring more demands.

What makes Peres think that this time will be any different? What has changed to make concessions a real alternative? It certainly isn't Abu Mazen, so what is it?
