Our participation in the United Nations must be only to use it as a communication via. The U.N. must not be a means to entangle us in world affairs, e.g. war.
As the only true world superpower, we must lead by example. We must reduce the size of the federal government dramatically, which will allow expansion of individual rights and the economy. Then those who want the personal freedom and economic affluence we exhibit can follow our example.
The Iron Curtain fell, not with economic sanctions or the Reagan Star Wars expenditures. It fell because the Soviet population was exposed to farmers with their own tractors and college students with automobiles, not to mention McDonalds. Then their own people demanded change and down came that evil empire.
We need the United Nations. But only as a means to expose our success to the world.
