I think that the USA is headed for a major breakup which will last for the next generation or so until the dust settles. I believe there will be several distinct state-groupings, and a vast reduction in Federal power. I think this will only be a good thing, because the power of the Federal Government is presently being despicably misused. It could be that by the end of this decade the USA retreats into a new period of isolationism as the country breaks up. Besides, as the weather gets worse and the Greenhouse Effect takes hold, the situation will become so chaotic as to overwhelm the financial capacity of the Federal Government. Consequently the FG will leave the states to look after their own affairs, which will only accelerate the breakup of the Union. It could be that in (say) 100 years time, the climatic situation may have become stable enough that some sort of power-sharing compromise could be arranged between the various state-groups. Perhaps then a new style of continental unity could be achieved, based on some form of lateral-linking inter-state cooperation rather than the current from-the-top Federal Power, which so easily becomes a form of fascism and tyranny.
