A. there will not be a war as long as we try to PEACEKEEP! B.we don't know if we are using nuclear weapons(Canda wouldnt even try. C.If nuclear weapons are used USA,RUSSIA,CUBA and other dictatorships will be blown to bits.
I read an article in Smithsonian magazine that World War III will most likely start and mainly occur in space, so if this is true, the (current) people able to fight would be the USA, Russia, and Japan. No one wins.
North Vietnam has the largest military, the U.S. is the most advanced, tough decision, but the US could just nuke the hell out of everybody. btw I like that Einstein quote.
We'll technically their have been mare then just 2 WW like the American Revolution could could because both France and Britain which both controlled a large portion of the world fought.
Anyway the winner in a conventional fought WW without any nukes with the current technology would be no one because no 1st world country would be stupid enough to fight a war that size knowing in the end their country borders would remain the same just with less population and industrial power because of the number of casualties. Also no one trying to take over the world could destroy the combined crazy of the US and Russia, Russia being crazy for burning their land to weaken enemy troops and moral then unleashing a huge counter attack after the Russian winter kills hundreds of enemies. The US being crazy of course for republicans and gangs also killing off 2% of our population during our civil war.
Sorry for any grammar or spelling errors it's 12 and in really. tired.
