I believe the question related to the 9-11 hijackers, not whatever terrorists you imagine there to be, lurking across the border, waiting to invade the US.
And IF one were a terrorist, where do you think you'd find the easiest point of entry for future "invasion"?
A direct flight from almost any part of the world straight into the US, which is the route most of the 9-11 hijackers took.
The Canadian government's not exactly clamping down on Islamic activity and movements.
How would you know? You've obviously made up your mind as to where terrorists originate, so I don't think you've bothered to keep up with anything happening in Canada.
Thankfully security will NOT be left to you at the border -- perhaps a girlscout and Gary Coleman covering 4,000 miles is sufficient for you JUST IN CASE...
[Easiest point for future invasion is] A direct flight from across any part of the world straight into the US, which is the route most of the 9-11 hijackers took.
And apparently you feel the MO for future terrorists will most likely be "direct flights", -- no doubt once again executed by four swarthy Middle Eastern types per plane. Who'd you have in charge of airline security -- Ray Charles himself??
I don't think you've bothered to keep up with anything happening in Canada.
Au contrar my Canadian friend -- I do know that your government just released 12 terrorist suspects due to a "lack of space" of which to keep them detained. I know JUST enough about Canadian "security."
BTW, take Peter Jennings back -- puleeese...
