There's only one source it appears, so far, but over the years they've proven themselves highly credible. Judge for yourselves:

It comes to our attention that the MEMRI Blog highlights an article from the Saudi al-Watan in Arabic that - according to an Afghan source - the United States is talking to the Taliban seeking to trade control of 5 provinces in exchange for the cessation of attacks on US bases. MEMRI summarizes:

An Afghan source in Kabul reports that U.S. Ambassador in Afghanistan Karl Eikenberry is holding secret talks with Taliban elements headed by the movement's foreign minister, Ahmad Mutawakil, at a secret location in Kabul. According to the source, the U.S. has offered the Taliban control of the Kandahar, Helmand, Oruzgan, Kunar and Nuristan provinces in return for a halt to the Taliban missile attacks on U.S. bases.

Kunar province borders the Khyber Pass region where the majority of US and NATO supplies pass enroute from Pakistan. And the remaining four provinces constitute fully the southern 25% of Afghanistan's territory.

MEMRI is a terrific site that I'd recommend you all bookmark this second. (via RedState)

Threat Watch's analysis on short notice:

What does seem logical is that an Afghan privy to the negotiations could have become (rightly) spooked that they might just pull it off, and leaked word in hopes that it might so anger American public opinion that the entire endeavor might be scrapped. That's the most logical explanation for motivation I see at the moment.

It would also fit in consistently with Ambassador Eikenberry's leaked cables recently railing against a 'surge' in forces in Afghanistan. He wouldn't voice such without thinking he has his hands on something else. Could this be it? The surrender of 25% of Afghan territory in exchange for some form of ceasefire?

One would hope not. But if so, this demonstrated type of 'effort' in Afghanistan would prove to be the strongest indication that it may be time to advocate the full pullout of American forces from Afghanistan.

If this is true, then not one more drop of American blood for a path that resembles Pakistan's path. You recall Pakistan's series of surrenders touted as agreements, right?

Yeah. How's that working out for Pakistan these days? And we want some of that? Do we?

We'll keep you posted.
