I mean, really: Ohhhhh shit.

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 repeated 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.

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.”

The intelligence budget of the United States is $80.1 billion annually. Just felt like interjecting that.

A man who had known Mr. Mansour years ago told Afghan officials that the man at the table did not resemble him. “He said he didn’t recognize him,” said an Afghan leader, who spoke on the condition of anonymity. … Last month, White House officials asked The New York Times to withhold Mr. Mansour’s name from an article about the peace talks, expressing concern that the talks would be jeopardized — and Mr. Mansour’s life put at risk — if his involvement were publicized.

Yeah, OK, this war is fucked.
