It really depends on what you consider a win and loss . US and Russia could most certainly nuke the middle east and make it a parking lot , but I don ' t think that they have the man power to invade the rest of the world . Round 1 is a no way . Only reason us and rus could win is if other countries don ' t step in due to not wanting to lose all the lives of their people . Round 2 they could probably do it , and they might be able to hold off the rest of the world with some very heavy casualties . But , they still have no chance at successfully invading the rest of the world . Offense is really , really hard . <| sep |> after 5 min of silence , the volume 9000 bullshit talk goes on . good ol jacko once saidI ' m starting with the Man In The MirrorI ' m asking him to change his waysAnd no message could have Been any clearerIf you wanna make the worldA better placeTake a look at yourself , andThen make a c h a n g e e e e e e e eeeeeeeeeeeeeeeeeeeeeeeee
