Hmmm. The US did in 3 mos. what the Soviets couldnt do in 10 years..
The three months is misleading in that sense, though. The Taliban weren't supported by another superpower. But the Afghanistan conflict in the '80s was really a hot point in the wider Cold War. The Soviet "local" best was against our covert/remote best. Unfortunately, the Taliban started believing that because they were able to drive out the Soviets with our help, they could do anything.
The Taliban are sexually confused, goat-herding drug lords with a penchant for SUVs and highway robbery. But Pakistan has nukes, and I don't believe for a minute that Pakistan is under strict control of moderates. We may wake up one day and find that Pakistan has had another junta, and by the way their nukes are all scattered over the mideast and are ready to fire unless Israel agrees to pack up and leave, America departs from the entire region, and India leaves Kashmir.
