Found this about Kissinger's Iran view. I agree with this.
What's wrong with starting with a meeting of diplomatic staff from Iran & US first, progress to level of secretary of state and then the heads of state meeting ? He didn't mention preconditions.

This really is not McCain's view. So Kissinger is kind of contradicting himself when he now says that he and McCain are in agreement.
