Now I am by no means an expert on anything relating to this topic, but this thought has come across my mind on several occassions.
To start with an example. I don't understand how someone could be for a thing like NAFTA, but against the UN. The way I see it is that globalization is either an all or nothing deal. If you globalize economically, then there has to be political globalization, and even to an extent, social globalization. If you want to protect the politcal sovereignty of the United States, then you should want to protect the economic sovereignty of the United States as well, right?
