The more we integrate with those cultures, the more we lose our sovereignty. Do you really want us to follow in the path of the Europeans?
I respectfully disagree that we lose our sovereignty when we cooperate closely with other countries having common interests. I am most certainly not an "internationalist" by any means. I believe our Constitution is one of our greatest assets, and we should preserve it according to its meaning as adopted. We are strong enough to befriend other smaller countries, and we actually make ourselves stronger by doing so. On the other hand, if you were a citizen in a smaller country to the south, how would you feel towards a larger neighbor with a much stronger economy that would shut you out of business with it? We are very fortunate that people in the Western Hemisphere have much in common with us, despite the different experiences they have had with government than we have had.
