There are only a few differences between Canada and the United States.

1. we don't carry small arms
2. we are generally polite
3. we only have one tenth the population with relatively the same lifestyle.
4.we share the longest unprotected border in the free world.

other than that, we have pretty much everything else the states has except a republican government.

Why would terrorists attack anywhere?
The attack on the world trade centre was an attack on the free world, not just on the united states.
The free world keeps it's headquarters in new york with the world trade organization and the U.N.
