The point stands. Bush is negotiating with Islamists in Iraq. We can disagree about the motivation but that is a cold hard fact. Interestingly, Bush receives very little criticism here for doing this. Double standard perhaps?
The US is backing the British and German negotiations, with the repeated public caveat that we do not consider a nuke armed Iran to be an acceptable outcome.
This is a perhaps subtle distinction, but a real one in light of the criticism that the US has taken for so-called unilateral action.
The double standard I see was in the US violating their doctrine on terrorists and terror sponsoring states WRT "Palestine". If we were following that doctrine for real, we would be shelling Ramallah from the sea instead of pressuring Israel to accommodate a viper in their bosom.
