As the world heats up, we need to head north, to stay cool. Canada, being northern, and their poor military, make perfect candidates for a quick, and easy capture of their country.
How will we accomplish this you ask?
Simple. Threaten them with nukes, who would be foolish enough not to surrender? When they surrender, send in troops to maintain order. Start devolving cites, to accommodate the growing world. With global warning on its way, in 50 years, America will be in flames, while Canada is a cozy 80'F
What strategies will be used?
When they surrender, troops enter Canada from Alaska, south into Vancouver. Seattle will head north to Vancouver, as well. New York, will send troops onto planes, parachute over Nova Scotia, and New Foundland.
I hope the US congress look over this matter.
