Who will have the upper hand?

Okay, just assuming that there would be a WWIII (but praying there wouldn't be), everyone should watch out for CHINA. They're pretty good technology wise but their manpower is what makes them a power to reckon with. So if there wouldn't be no nukes involved, I'd bet on China.

I think if there will be a world war there will be no winner is it will be very destructive with nuclear weapons in many hands nowadays, most probably some country that didn't join the war and was less effected by the destruction will emerge as new world power (maybe Australia or Brazil?) but again there will not be much of the world left to dominate :( let's hope there will be no more wars. peace to all :)

This may sound far fetched, but I think if WWIII broke out it would cause enough disruption in the universe, and the Aliens would come and wipe out all electrical technology, and man would have to start all over again electrical wise, because the Aliens would destroy, and confiscate anything that would be a destructive weapon to the universe, maybe even destroy all the negative people involved, and allow the good people to take over, clean up and fix the world... I think that is where the upper hand would be, either that or the world would shake all her fleas off. - DNatureofDTrain

i think in war there is no winner. we are all losers in war. as to who will get the upperhand, its hard to tell. there are many great countries out there with great military powers. often times there strength in terms of arsenal, weaponry is not so well revealed. we just get shocked that a country (we never thought is capable of having)is hiding nuclear weapons.
