I do not keep up with politics, so I do not know the details of this border situation, but the key for me is the cooperation between Canada and the U. S. If the facts are true that terrorist attempt to enter the US thru Canada, then it would seem to me it would be in both country's interest to improve border security. Obviously, it is a huge undertaking because securing that many miles seems almost impossible, as with Mexico. So cooperation is the key. If cooperation cannot be "grown" so to speak, then we have to step back and ask why. I mean Canada is not a stupid country, and I found that entering and leaving Canada seemed more difficult than entering the U. S., altho I have only been thru that experience once. So those are my thoughts. It is more about the dialogue between the two countries than it is whatever logistical arrangements are made about protecting the borders.
