It's being suggested by an increasing number of bloggers, pundits and anti-war activists that Afghanistan has become this generation's Vietnam. Critics of the war say that, like in Vietnam, we are spending billions supporting a corrupt regime in an unwinnable war with no end game and ever-increasing casualties, both military and civilian.
No one quite knows what would happen if the United States were to simply leave Afghanistan - the Taliban could take over again and it could be as bad or worse as it was before we arrived - but critics of the war say that while the Taliban is still there, Al Qaeda is virtually out of Afghanistan. The really significant battles now being waged, many war analysts say, are the more clandestine ones taking place in Pakistan's tribal regions with San Diego-made drones (unmanned aerial vehicles), NATO helicopters, super-secret special operations military forces, and CIA.
