US Pulls Back on the Use of Air Strikes in Afghanistan

The US has used airstrikes against the Taliban in Afghanistan, but the cost may be higher than any benefit received in combat. General Stanley McChrystal said last week that "air power contains the seeds of our own destruction if we do not use it responsibly," adding, "we can lose this fight." So he's placed new restrictions on the kind of airstrikes that have killed many civilians. Nancy Youssef, chief Pentagon correspondent for McClatchy Newspapers, has been reporting from Iraq and Afghanistan.
