Micro, the fundamental problem here is that the ANA and the US allies in Afghanistan are not fighting for freedom - they are fighting for a kleptocracy that by some accounts is actually more oppressive and dangerous to live under than the Taliban (it is without a doubt more capricious - Karzai's government doesn't appear to have any control over its own.)
The high levels of support for the Taliban as an alternative make sense. Why would anyone help a foreign government install a bunch of thieves and rapists (that's one of the most common complaints about Afghan officials)?
The Taliban's military and organisational skill has made it an acceptable alternative, and one that's eventually going to retake the country barring some miracle. Lots of bombing (already happening), again, has resulted in a Taliban that is stronger.
Mullah Omar may be a bad dude - but he's a better option in the eyes of the Afghans (and the "progress" over the last ten years proves it) than what we're offering.
