By what TL or alternate series of historical developments can we have the U.S. develop into the loosest and most decentralized of governments, with all the states within being basically sovereign. I want to maximize this state of decentralized confederation to the point that by the modern day, the Union controls all it's states as little as our modern day U.N. rules the world. With each state being as sovereign as a nation would be, albeit in a much different political situation with somr sort of Union remaining with all the other U.S. states.
