Being a logistical nightmare has made Afghanistan a costly place to wage war. In the course of debating General Stanley McChrystal’s request for 40,000 additional troops, lawmakers uncovered the fact that it costs $400 a gallon to fuel the vehicles and planes the Pentagon is using to fight the Taliban. Afghanistan lacks a seaport of its own, so fuel must first be shipped to Karachi, Pakistan, and then trucked all the way into Afghanistan, driving up transportation costs of moving fuel.
