no they are not the united states. im sure each of those countries has federal govts as well.But the free movement you speak of works in the same way. And the EU has a federal government in Brussels. So they're essentially the United States of Europe. Did you notice how difficult it was for the U.K. to extricate itself from it?
if US wanted to be like them then it would have to have free movement with canada for example. u guys dont have it in you to do that....well based on what i seen on here i dont think so, maybe theres a poll out there that shows high support for such a thing.
theres something in the work for free movement with english common wealth countries.
