From the Times' story:
For months, the secret talks unfolding between Taliban and Afghan leaders to end the war appeared to be showing promise, if only because of the appearance of a certain insurgent leader at one end of the table: Mullah Akhtar Muhammad Mansour, one of the most senior commanders in the Taliban movement.In most parts of the world you can't even cash a check without confirming who you are, but apparently the current administration regards such formalities, when applied to those who are trying to kill us, to be unreasonable impositions.
But now, it turns out, Mr. Mansour was apparently not Mr. Mansour at all. In an episode that could have been lifted from a spy novel, United States and Afghan officials now say the Afghan man was an impostor, and high-level discussions conducted with the assistance of NATO appear to have achieved little.
“It’s not him,” said a Western diplomat in Kabul intimately involved in the discussions. “And we gave him a lot of money.”
American officials confirmed Monday that they had given up hope that the Afghan was Mr. Mansour, or even a member of the Taliban leadership.
NATO and Afghan officials said they held three meetings with the man, who traveled from Pakistan, where Taliban leaders have taken refuge.
President Obama campaigned on the promise that so far from following his predecessor's maladroit handling of foreign affairs his administration would usher in an era of "smart diplomacy". I'm not certain what that entails, but I'm pretty sure it should mean that we negotiate with actual representatives of the other side and not with whomever walks in off the street.
