It's a classic cold war communist tactic used in Korea and in Viet Nam...when you can't win on battlefield or need time to take pressure off, you negotiate to get when you can't get on battlefield.
I can just see all the appeasers and peaceniks responding to this one. Same folks who think we should be negotitating with bin Laden. Our adversaries do not want peaceful coexistence, they want to undermine and ultimately dominate and eliminate ANYONE not aligned to their belief system.
