I have not seen one cogent argument why the US taxpayer should be funding the role of policeman indefinitely in faraway lands.

Terrorism in Afghanistan has zero to do with the US constituency.

A "foothold" is useless and unnecessary.

I feel badly for the Afghan people, but ultimately it isn't the US' problem, and never has been. If they'd like to have a civil war and get those assholes out, let them.
