For decades, the peaceful and virtually unguarded continental perimeter around North America was the pride of both Ottawa and Washington. In a post-September 11th world, however, this cannot be taken for granted. The long border between the United States and Canada enjoys the largest trade relationship in the world.[i] The unhindered movement of goods, capital and labor across borders, however, can and has been, abused by international aggressors to exact violence on innocent civilians.
On September 11, 2001 a group of 19 men created havoc on the United States and, by extension, the rest of the Western world. Armed with box cutters and just enough flight training to take down four commercial aircraft, these 19 men murdered nearly 3,000 civilians. Similar attacks later took place in other relatively free societies such as England and Spain.[ii]
