California? If Bush is smart, that's exactly what he'll do. As long as it stays inside Kalifornia.
OK, how about this scenario. Say California announces they're secession. The walk away from the Union asking nothing in return. They seize all military bases, Navy ships in San Diego, all airplanes, all tanks, etc. They announce they're withdrawing from the war in Iraq and demand the return of all California National Guard troops over there. They also announce that they're not responsible for any part of the national debt or social security obligations. Finally, they announce that goods destined for the U.S. are free to be landed in California ports, for a "small" tariff fee. What does the U.S do in response?
