Clinical Narcissist

Martin Peretz, editor of the New Republic and an Obama supporter in the primary and general election, voices a very damning thought, which can only be considered a rather complete change of heart about his candidate, I think:

So this question arises: If Obama could not get Chicago over the finish
line in Copenhagen, which was a test only of his charms, how will he persuade
Tehran to give up its nuclear weapons capacity or the Arabs, to whom he has
tilted (we are told) only tactically, to sit down without their 60 year-old map
as guide to what they demand from Israel.

What I suspect is that the president is probably a clinical narcissist.
This is not necessarily a bad condition if one maintains for oneself what the
psychiatrists call an "optimal margin of illusion," that is, the margin of hope
that allows you to work. But what if his narcissism blinds him to the issues and
problems in the world and the inveterate foes of the nation that are not
susceptible to his charms?
