The Mexican border is NOT about middle eastern insurgents its about Insurgents of another kind.. Middle eastern terrorists have the money to FLY into the U.S.(from Canada or ANYWHERE) if only for a "visit"(wink, wink).. They don't NEED to sneak in..
20 plus million brand new DEMOCRATS(from across the border) are/is a good thing WHY?..
Do not deceive yourself. The primary difference between Canadian and Mexican policy is when the money is collected. Granted, Mexico has a crap economy. I have not seen a published statement from either government stating that they would secure THEIR side of the border. So it is a crapshoot as to which one will say "sorry, but the US brought it upon themselves again". My opinion is that Mexico is the most corrupt, and the greatest threat. But you can never be too sure....
