A more likely scenario is that Mexico will invade the southwest, Russia will invade Alaska, and the Canadians will take over shipping in the St. Lawrence River. At that point The Northeast states will declare gay marriage as the law of the land and because of that The South will secede, taking along wit it Texas and Louisiana. The northeast states will declare war but we'll simply cut off the oil and natural gas pipelines to them. Maybe Japan will take over Hawaii and what's left of California and the west coast.
Aaahh glock.... that's what happening now...
