Only 35% of International Security Assistance Force's (ISAF) logistics for this occupation or war are dependent on Pakistan.
Suspected militants in southern Pakistan set ablaze more than two dozen tankers carrying fuel for foreign troops in Afghanistan on Friday, highlighting the vulnerability of the U.S.-led mission a day after Pakistan closed a major border crossing.
And on the same day, another supply route to Afghanistan was closed by the Pakistani government after fighting that led to the deaths of three Pakistani soldiers.
The story behind this was that Pakistani soldiers manning a post fired upon American helicopters. Fire was returned and obliterated the outpost.
But the really good news is that only about half the cargo that flows into Afghanistan comes in via one of the two gates from Pakistan. Another 30 percent uses two major routes through Kazakhstan and Uzbekistan, one via Russia and the other via the Caucasus. The remaining 20 percent -- mostly sensitive items like weapons, ammunition and other critical equipment -- comes in by air.
