@ Musashi_kenshin:
No, now that the mess is made, there would be no point.
That doesn't mean that it would be wise to get tangled into it for those who aren't already.
I'm not sure whether there still can be any form of success or whether its already too late. I think it is too late, but a step into the right direction would be to separate the terrorist hunters and the nation builders again as it was in the beginning. The only way to win this war would be to win the hearts and minds of the natives. They started to hate the "enduring freedom forces" and the more the other troops there are associated with them, the more they hate them too.
Like i said, i think its too late. Now that the Taliban are back and have more support by the civilian population than ever, we of course cannot ignore them and try to go on with the nation building process. But fighting them is no use either. You simply cannot win such a war. Its like the mythical Hydra. For every head you chop off, two new grow. There are about half a million young men growing into a combat-able age every year over there. The more of them or their fathers and older brothers you kill, the more will join the resistance. We are in pretty much the same position now as the Sovjets were in the 80s. We got a friendly but powerless pupet regime that is dispised by it's population and doesn't even rule the capital city undisputed, hundreds of warlords, a ever growing drug traffic that cannot be engaged without driving the population even further into the arms of the Taliban, an endless supply of new guerilla fighters and foreign powers which finance and support them. If they even need help with all the drug money they are making.
Honestly, i have no idea what to do to acomplish the initial mission now. It might have worked before the population became pissed off with the NATO forces, but now...
What i know is that the useless fights and "victories" of killing a few hundred Taliban is definitely not making up for the negative effects this battles and the collateral damage they cause have on the population. Kill a Taliban and his two younger brothers will take his place. Kill a innocent bystander and dozens of young men will join the insurgents. And at some point you will reach a point at which even women, old people and children will start throwing stones every time they see a foreign soldier.
