In action movies, a fairly standard plot is to have terrorists that are trying to destroy Washington, DC. Let’s suppose for a moment that one of them actually succeeds. Our nation’s capital is wiped off the map, and the President, Vice President, Cabinet, Supreme Court, and Congress (most of them, at least) are all dead. The federal government is decimated; not even Strom Thurmond survives the cataclism.
My question is: what happens now? Is the USA dissolved, or do the 50 states just set up a new federal government somewhere else? Could 49 of the states get together and kick out California? Could I get away with not filing my income tax that year?
