Project for a New American Century's "office" in DC is just a mail drop.
Project for a New American Century lists their office address as 1150 17th Street, Suite 510, Washington DC on their web site front page. http://NewAmericanCentury.Org But, like their misleading advice as a "think tank" this a phony "mail drop" address.
PNAC presented a report called "Rebuilding America's Defenses" written mostly by Chicken Hawks who never joined the military. It said that "it will take a catastrophic and catalyzing event, like a new Pearl Harbor" to get the American public's support for using our military might. Like their "military leadership" the PNAC was about false appearances instead of truth. The PNAC, hiding behind a phony office "front", with a misleading web site, helped get America in to a war over false pretenses.
