The Pentagon has hired the Rendon Group, a well-known Washington public-relations firm, to help it explain U.S. military strikes in Afghanistan to global audiences. Rendon will be paid $397,000 over the next four months to monitor news media in 79 countries, conduct focus groups and create a counterterrorism Web site. Rendon's help is needed because "we are clearly losing the 'hearts and minds' issue," said one official involved in the administration spin effort.
