Over the next several months there will be a battle for hearts and minds, but not in Iraq or Afghanistan. The war will be here at home, waged mostly in the halls of Congress, where grim lobbyists for one of the top 15 economies in the world are digging in to preserve their stake in the massive U.S. military budget. With the country in deep recession and resources dwindling for the new administration’s programs on health care, education, and the environment, the outcome of this battle may well end up defining the next four years.
