"Then is the phenomena we are seeing with Neocons the start of something new? Centrally planned economy of the entire world?"

I think that the "Neocons" are just one manifestation of the growing realization of a global economy. I think that they are attempting, whether wisely or un (I think un) to see to it that the USA has SOME say in that inevitability. And the Neocons do not accept the notion that the USA is the impetus for all international unrest.

The other side is just as "internationalist" -- they just see the USA as a bad influence on the world and think that with the oncoming globalization, the USA should shrink in influence and importance. They want a centrally planned economy too. They just believe that everyone except the USA is predisposed to peaceful coexistence.
