Baires, there's not much that will stand in the way of a few US Armoured Divisions. It's about the last thing that the US does way better than anyone else. They've never tried it in Latin America yet but if the brown stuff really hit the fan in Mexico, right on their door step, do you think it wouldn't happen?

The trajectory of NAFTA and the Amero is a North American Union of some kind. The occupation and de facto annexation of Mexico doesn't seem altogether implausible to me if they really let things slide into chaos down there and some undesirables seized power. That's what the Brits would have done 100 years ago. Nothing like a war to takes one's mind off other problems!
