That's an interesting question in a lot of ways, it seems that some countries disintegrate around ethnic and historical lines; I'm thinking of the former Yugoslavia, and the former Czechoslovakia.
What used to hold the United States together was both the United States Constitution, and the Bill of Rights, interpolating times of great progress, and non interference by foreign controlled central banking. Every president that has got rid of, or thought about getting red of Rothschild banking has been assassinated, except for the very lucky Andrew Jackson, who's assassin misfired.
The banker's dreams of a New World Order. . . .will be nothing but an awful joke, and a sad time for the history of the world, when they are "realized."
