You know, throughout history the U.S. has always wanted Canada?
Maybe the SCOTUS just cleared the way for Canadian alarmists to claim possible annexation, but Good God...why would we want them? It would seem few Canadians like the U.S. They're already imploding economically from their National Healthcare system costs and living up to those God Awful Kyoto Protocols.
Probably be smarter just the annex this whole Western Hemisphere. That would control our borders and out with the dictators.
