Diplomacy is a means of getting what you want.
If Osama Bin Laden is willing to sit down to discuss how he should be killed and his organization dismantled, we should do it.
And all this nonsense aside, Iran and the US potentially have huge areas of mutual interest as it pertains to theater politics, Iraqi border issues and potentially trade......remember all those years of talks with the Soviet Union when we still had missiles pointed at each other.
Good diplomacy isn't about giving away, it is about getting more.
