The US Constitution

[JoyAnna]

I worry that having only one central government for the world will result in an impossible set-up for checks and balances against tyranny. What we need is to restore the Constitution in the US, not try to transplant it with only one central government for the whole planet. It would be unmanageable. Too much distance between the central authority and the individual.

Yes, but –– if the constitution were adhered to faithfully (both across the planet and in the USA) the concept of 'central authority' would not be an issue. The state governments would deal with all issues not specifically allocated to the central government.
