While I accept what you say about the Taliban, I think it's equally important not to mistake the reason why the US are involved there. It's certainly not because the Taliban harboured terrorists. That actually makes you a 'special friend' of the US in many circumstances. It's not even because in this particular case, the terrorists they were harbouring happened to attack the US. It's because Afghanistan is sitting smack in the middle of Russia, Iran, China, Pakistan. It's geopolitical importance can't be understated. The US couldn't give a flying fuck about whatever atrocities were being committed there by the regime they left in charge, nor whatever atrocities are being committed there by the Taliban OR the US troups, OR the 'Nothern Alliance' ( who are just as bad as the other 2 ), nor whatever atrocities will be committed by whoever is left standing when the US are finally chased out with their tails between their legs. In a slightly less fucked-up world ... sure ... some benign superpower could step in and remove the Taliban without killing 1/2 of the civilian population in the process, then somehow leave the country gracefully and watch a vibrant new democracy evolve. This is NOT that world. The US is NOT that benign superpower. This war is NOT just, and nothing good will come of it.
