U.S. troops go back to Pakistan

U.S. military officers are back on Pakistani soil. According to Reuters, this suggests the two sides may be working together more closely after a series of setbacks and the Pakistani government's insistence the U.S. apologize for the accidental killing of 24 Pakistan troops in a cross-border incident last year. Their jobs are to improve communications between ISAF personnel and Pakistani troops in Afghanistan. Yet to be resolved is the shutdown of the Pakistani border to shipments of supplies intended for NATO troops.
