Of course it does. Our founding fathers wrote that single, clear, concise sentence and placed it, like a bow sprint on a mighty sailing ship, at the foremost position of our most sacred, legal document. There it remains unmodified by war or political ambiguity from that generation to our own.
Defense is clearly a federal responsibility.
Individual citizens have, from time to time beginning with Benedict Arnold, sought to undermine our security either because they covertly served an alien ideology or because they sought personal reward. During the past several years, two alarming trends have grown to such huge proportions that we as citizens should fear for our own safety. The first of these is the dramatic increase in incidents which adversely affect national security. Almost one year ago I issued a press release about the Cox Report, which warned that lapses in security in the Department of Energy exposed our country's most vital nuclear secrets to exploitation by foreign agents. It was a warning that was only half heard - another case of too little, too late.
