Look, Sirs, your campaign of "kill the messenger" is totally inappropriate. I'm presenting things to think about, in a very competent fashion. I am not politician nor praytell a president. They are judged by their (voluntary) stations in life. It is my right, nay duty, to criticize, and I do so in a constructive spirit, regardless of your vicarious thin skin. Live with it.
As to the particulars of talking with Syria and Iran, I would defer to James Baker and Lee Hamilton, who recommended it, and a host of prestigious commentators, who have spoken favorably of it. But I will add my own thoughts: talking is the preferred, favored mode of international relations. That stems from the fundamental human truth that you're not likely to resolve differences when operating in the dark about your opponent's wants, needs and aspirations and without a "bridge of communication" being established upon which future "settlements" (in the metaphorical physical sense, and the literal diplomatic sense) can be based.
We had communications with the Soviet Union during the frigid days of the Cold War, and Nixon, famously, endorsed the principle of "talking things over" in his overture to (and success with) China. The examples abound. Indeed, obverse examples abound.
What the particular strategy would be beyond establishing relationships and channels with presumed hostile governments is a matter I don't have to flesh out. It involves an assiduous process of setting (realistic) goals and a strategy to achieve them, replete with "a list of possible concessions," "a list of possible gains," prioritizing them, compartmentalizing what can't be dealt with now or is legitimately beyond the scope of the talks, and so forth, seemingly ad infinitum, in a process that can be masterful in the hands of a true statesman, like ... you fill in the name. All the while the main objective is to establish and keep civil, respectful, even friendly relations as a good in itself: a platform where matters can be discussed short of just throwing up your hands and saying, "Bring it on."
