The defence diplomacy of the United States in the midst of the current war against terror in Afghanistan is designed towards ending the US military operations without ceding total authority to the Taliban. The US-led international coalition of forces, that include NATO forces, have failed to crush the Taliban. On the other hand, Taliban have been unable to force the external forces to quit Afghanistan. The US does not want to quit without the assurance that no second 9/11 takes place. Simultaneously, the cost of war is increasingly becoming prohibitive especially when the country is in the midst of a hard recession. Washington’s war and diplomacy in Afghanistan is currently at a crossroads. This article examines and analyses US defence diplomacy in the region to resolve the Afghan tangle.
