The smart ones make the bombs inside the country. When has anyone ever tried to drive a bomb across the border? Hell, this is the same thing as airport security. They could just drive the bomb into the mess of cars at the border before being inspected and it would have the same effect. It would be even a more spectacular effect if done on a bridge (i.e. Ambassador (Detroit-Windor); Peace Bridge (Buffalo,NY); Rainbow Bridge (Niagara Falls)) because then it would strike fear into people about not being caught in the blast but being on the bridge that is collapsing (Hollywood milks this one all the time).
The vast majority of the US/Canadian border is unguarded and there are hundreds of roads the guy could have alternately taken.
Any sophisticated attacker would realize this and simply go a few miles out of the way to one of those logging roads.
I hardly think that your example offers evidence that border security enhances national security, only that it did in one isolated instance (with a very stupid terrorist).
Odds are if the terrorist failed to realize he could cross the border without being screened, he would have made some other mistake that would have foiled whatever his planned attack was.
