No Good Reason

Via Billmon, we learn that the Taliban is mounting an offensive in Afghanistan:

In the past three months, the United States has carried out 340 airstrikes in Afghanistan, twice the number in Iraq.

Officials told The Washington Post the military has been responding aggressively to Taliban aggression.
"I think the Taliban realize they have a window to act," said Army Maj. Gen. Benjamin Freakley, who commands the U.S. mission in Afghanistan. "The enemy is working against a window that he knows is closing."

The Taliban has been especially active in southern Afghanistan in recent weeks. The toll includes the deaths of 300 civilians, insurgents and soldiers and the burning of 200 schools.

How can it be that we have not yet defested the Taliban?
