Officials say Pakistani President Pervez Musharraf's instituting a state of emergency has currently not altered the supply routes through Pakistan, but preparations are being made by top U.S. military officials in case things should change, the Pentagon reported.
The supply lines are "a very real area of concern for our commanders in Afghanistan, because 75 percent of all of our supplies for our troops in Afghanistan flow either through or over Pakistan, " Pentagon press secretary Geoff Morrell said in a statement.
"Supplies to our troops in Afghanistan continue to flow freely through Pakistan, and for that we are grateful. But the U.S. is not taking the passage for granted. Planners are working on contingency supply lines to our troops if it becomes necessary to alter the way we now support our troops."
Morrell did non address specifics regarding what the contingency plans detail but said a plan B has been discussed.
