It does make it defunct, even if it is a fact. You posted a scenario, and then immediately followed with how it was meaningless...making it defunct.
EVERY country out there is powerful because of its relations with other countries. NO country out there would be what it is today without its support...I don't know why you don't get that. If every country somehow became independent, solely working in the chaos of internal work only... the USA would most likely be on top.
And that's a horrible analogy. COD and Socom have nothing to do with each other. You're basically comparing the power of the US to that of the Martian Military.
