If you criticise capitalism one of the most likely responses you're going to get is ''so you want to become communist like the SU"?
And that wkkipedia article is of course not proving that trade equals capitalism (or are you saying that America stops being capitalistic if Trumps dream of a self-sufficient nation somehow succeeds?). Trade is trade. There was trade in the past when capitalism did not yet exist and there will be trade in the future when capitalism no longer exists.
