@sbrob,
Staying the course means continuing an illegal invasion of a sovereign nation, which is a war crime.
The Afghans can take care of their own country. They have immense wealth in natural resources, they are in a position to market by pipeline one of the richest areas of oil in the world. This is why the US is in Afghanistan. This is why the US should get out of Afghanistan. The US has caused way too much grief and suffering with its political machinations over the last 20 years.
