Gee, sorry.
Guess I'll have to start writing my congressladies about barricades and infantry along the northern perimeter.
On your behalf, you're right about the known 9/11 crew but it might be considered a part of being a good neighbor to at least make an effort to avoid being a conduit for all the other illegals that DO come from the north.
I might add that those 1,000 troops would be far better utilized doing a security job on this continent than escorting yet-to-appear UN aid convoys in Afganistan.
But that would be whining.
