as far as the USSR being communist, then the USA is a free nation.
Perhaps. But it hardly speaks well of Communism that every large scale attempt at it has been comparably a failliur. Of course, you could say the same about democracy, at least in so far as we've never had a full and perfect democracy, so perhaps this point ultimately proves nothing.
The USSR wasn't communist, it didn't represent the community. It essentially merged corporations and the government. And the US isn't supposed to be strongly democratic, it's supposed be republican. Though it seems that the tend is towards making it more democratic and less republican.
