I don't know about empty, but it would be about 20% lighter...

Answer 2

It already is undefended, except a few border agents. Which is why we have so many illegals here already. We need to start prosecuting companies that hire illegals and start hunting down those who have invaded our country.

Answer 3

Too many Americans would try and escape!

Answer 4

Undefended? Who says the Canadian Border is free of security and crime?
