Ok. Coffee break trying to fend off a migraine.

First, I've got the book Merger of Century flagged to download from the library when I get home.

My instinct is to think there would need to be a big shift in governance.

Reorganize into 3-8 regional federations joined in a confederation. The National government would be restricted to foreign affairs, military, and charged with defending and upholding the civil rights of the individual.

The regional federations would outside the arenas of international affairs and military would function more like the current national governments but be smaller.
