I think (guessing) that the theory they are going for here ascribes to the "I don't know with what weapons WW3 will be fought, but WW4 will be fought with sticks and stones" idea...
More specifically, that is to say that it assumes WW3 will have already happened beforehand, and that the war it is talking about will come after, perhaps as a result of said WW3...
Though the difference with Raz0rfist/almond's version is that they are assuming these nation states will remain intact throughout, at least the third World War, whereas Einstein, at least apocryphally, seemed to think that it would result in them "Returning to Monke"TM...
