I don't think they could do anything I mean if we really control all the governments of the world then we control all the armies too and thus all the weapons. There really couldn't be any sort of resistance...what could the people do? Besides if it meant world peace because we were all one country people might even be into it as long as they could keep living their lives like they want which seems to be the case right now...I just don't see a benefit to hiding it if you have that kind if power...
