The U.S. focus on Afghanistan largely centers on withdrawing most forces by 2014 and reducing the cost of the war. These are important issues: By the end of fiscal year 2013, the United States will have spent $560 billion on the war, and current annual costs are more than $110 billion.

It is, however, far easier to talk about troop levels and budget cuts than to plan and conduct a real-world transition to Afghan responsibility for security and funding of Afghan operations and to deal with the strategic realities involved. The United States needs to come to grips with a range of extremely difficult issues, none of which involves good options.

First, Washington needs to reassess its strategic interests in Central and South Asia and whether these call for continuing a major commitment of aid to Afghanistan and Pakistan after a U.S. withdrawal. The answer may well be yes, but some argue that the best way to play the new great game in the region is to leave things to Russia, China, Turkey, Iran, India and the Central Asian countries.
