There are no "Taliban" apart from the Pashtun in general, and they have no ambitions beyond Pakistan and Afghanistan, or even only the Pashtun areas of those countries, where they did at least stamp out the opium trade and the endemic pederasty. Unlike us. We brought them both back.
Who do you think is going to leave Afghanistan first? NATO? Or "the Taliban"? Which of them will ever leave Afghanistan? Which of them has anywhere else to go? Don't take my word for any of this. As of today, just ask Hamid Karzai.
What he cannot tell you, however, is what any of it was all for from our own point of view. May we now expect an apology from those who have given us 10 years of war for nothing?
