Here‘s what Yasser Arafat never did:

RAMALLAH, West Bank – Reacting forcefully to Hamas rocket and mortar fire in the Gaza Strip in defiance of a cease-fire with Israel, Palestinian leader Mahmoud Abbas dismissed his top security commanders Thursday and sent a message to the militants that he will not tolerate further truce violations.

Among about 20 senior officers who lost their jobs were the top two commanders, Brig. Gen. Abdel Razek Majaidie, chief of public security, and police chief Saeb al-Ajed, security officials said, a clear sign that Abbas is serious about enforcing the two-day-old truce.

Abbas is serious about peace. I think Sharon is too, which makes sense in a crazy sort of way. These are historic times.
