How Much Is Afghanistan Worth?

Michael Yon writes:

Beyond the fact that we will need to dedicate decades or even a century to Afghanistan, no country in the neighborhood will cooperate except when it directly affects their own interests. They will attempt to squeeze every dollar and concession from us as we help secure their neighborhoods, all while the present drug-dealing Afghan government is bucking like a mule while our government is preparing to pin a significant amount of our combat power in a landlocked country.

The sum of many factors leaves me with a bad feeling about all this. The Iraq war, even during the worst times, never seemed like such a bog. Yet there is something about our commitment in Afghanistan that feels wrong, as if a bear trap is hidden under the sand.
