Imagine you’re a villager living in southern Afghanistan.

You’re barely educated, proud of your region’s history of stopping invaders and suspicious of outsiders. Like most of your fellow Pashtuns, you generally dislike the Taliban because many are overzealous, truculent nutcases.

Yet you are even more suspicious of the infidel American troops. You know of some villages where the Americans have helped build roads and been respectful of local elders and customs. On the other hand, you know of other villages where the infidel troops have invaded homes, shamed families by ogling women, or bombed wedding parties.

You’re angry that your people, the Pashtuns, traditionally the dominant tribe of Afghanistan, seem to have been pushed aside in recent years, with American help. Moreover, the Afghan government has never been more corrupt. The Taliban may be incompetent, but at least they are pious Muslim Pashtuns and reasonably honest.

You were always uncomfortable with foreign troops in your land, but it wasn’t so bad the first few years when there were only about 10,000 American soldiers in the entire country. Now, after President Obama’s speech on Tuesday, there soon will be 100,000. That’s three times as many as when the president took office, and 10 times as many as in 2003.
