Please. Calling soldiers shooting children murderers doesn't mean I like the Taliban, it means I don't want our soldiers murdering children. Really, this isn't complicated.
The Taliban might have been evil, but it doesn't mean that the replacements will be any better. As near as anybody who isn't a jackass can tell, the US has inserted ourselves into a pair of century (millenia?) long sectarian conflicts. Government barely exists 100 miles from the Kabul. These warlords were fighting each other before the Taliban, somewhat subjugated by the Taliban, and will be fighting each other again after we finally leave. All we've done is inflicted horrendous collateral damage on whoever happened to get in our way while mouthing trite bullshit about democracy. In order to leave the citizens of the country in a position that will be, at best, no better than under the Taliban. And probably much worse. We've killed how many in order to install some thug and his drug / warlord brother atop the heap?
As for Wikileaks, after Bush decided to run black prisons and endorsed the torture at Abu Ghraib, I frankly stopped believing anything out government says. Obama, with his support of the Afghanistan war and Bush era spy laws, has more or less endorsed Bush' view of civil liberties and demonstrated that the US government is worth the trust of exactly nobody. I'll believe what the government says when Bush is executed for war crimes, and there are a long line of US Generals up there with him. In light of those facts, Wikileaks is a force for good. Since we've demonstrated that morality and probability of success have no impact on our decisions, perhaps Wikileaks can damage the war effort enough to get us out of Afghanistan. Frankly, the less Americans trust their government, the better.
