You have to negotiate from positions of strength. And right now with Iran, we're not negotiating from a position of strength. The Europeans are negotiating from the position of "Please give up your nuclear weapons program, and by the way if you do we'll give you several boatloads of carrots." The Iranians are quite willing to keep on negotiating on that line for a long time.

There is no patriotic obligation to help advance the career of a politician who is otherwise pursuing interests that are fundamentally antithetical to your values. That's not the call of patriotism.
