President Bush also said, "We'll never know the names of all who perished, but at this sacred place, communism's unknown victims will be consecrated to history and remembered forever. We dedicate this memorial because we have an obligation to those who died, to acknowledge their lives and honor their memory." Bush equated communism to the threat of terrorism then facing the U.S.: "Like the Communists, the terrorists and radicals who have attacked our nation are followers of a murderous ideology that despises freedom, crushes all dissent, has expansionist ambitions and pursues totalitarian aims."
