If all 50 states went to war, which one would win?

[Redalgo]

It depends on which states' leaders are willing to go how far to win. In theory it could be whichever state gets its hands on the President's football first, whichever is quickest in salvaging fissile material from the warheads to create radiological weapons, or - in the case of Georgia - the government's willingness (or lack thereof) to risk setting off a global smallpox pandemic.

Even the slightest of possibilities of in-fighting between American republics illustrates once again how utterly batsh**t insane it is for a country to maintain advanced, sizable arsenals of WMDs.

It would not be a long enough conflict - hours or at most a few days - so the populations, economies, and technological prowess of each state would have negligible affects on the outcomes. If you want to explore another hypothetical of the states creating alliances I guess it would get a lot more complicated.
