Colonel , offers his sober assessment:
(h/t James Fallows)Since early 2002, more than 2,000 Americans have been killed there, with many more seriously wounded. Thousands of Afghan civilians have been killed too. The United States has spent close to $1 trillion trying to turn Afghanistan into a modern, functioning state.
What has the United States achieved? The place is more violent today than it was at the height of the Afghan surge of troops under Gen. Stanley McChrystal in 2009, the government is one of the most corrupt in the world, and the ability of the Afghan security forces is dubious at best.
Would Afghanistan have been worse off today if the United States had left soon after toppling the Taliban and crushing Al Qaeda? Remember, the United States had essentially accomplished its core political objective in Afghanistan — the destruction of Al Qaeda there — by early 2002.
