From today's edition of The New York Times:
In Washington, American officials were scrambling to assess what had happened amid preliminary reports that allied forces in Afghanistan engaged in a firefight along the border and called in airstrikes.
If this is the case, then the use of force was likely justified to an extent that no one should be punished. The facts will ultimately determine the proper course of action.
However, on a separate front, the U.S. still remains seemingly oblivious to the need to devise and put in place alternative supply routes. As a result, it continues to subject itself to avoidable vulnerability in the logistics area. For now, Pakistan continues to prevent the passage of supplies and, unless the avoidable vulnerability is addressed, will remain in a position to "turn on" and "off" the passage of supplies at its whim. Periodic disruptions and the threat of disruptons of supplies do not help military planning and operations.
