The Pentagon is steadily and dramatically increasing the money it spends to win what it calls the human terrain" of world public opinion. In the process, it is raising concerns of spreading propaganda at home in violation of federal law. An Associated Press investigation found that over the past five years, the money the military spends on winning hearts and minds at home and abroad has grown by 63 percent, to at least $4.7 billion this year, according to Department of Defense budgets and other documents. That's almost as much as it spent on body armor for troops in Iraq and Afghanistan between 2004 and 2006. This year, the Pentagon will employ 27,000 people just for recruitment, advertising and public relations - almost as many as the total 30,000-person work force in the State Department. The biggest chunk of funds - about $1.6 billion - goes into recruitment and advertising. Another $547 million goes into public affairs, which reaches American audiences. And about $489 million more goes into what is known as psychological operations. Staffing across all these areas costs about $2.1 billion, as calculated by the number of full-time employees and the military's average cost per service member. That's double the staffing costs for 2003. Recruitment and advertising are the only two areas where Congress has authorized the military to influence the American public. Far more controversial is public affairs, because of the prohibition on propaganda to the American public.
