Here's how it'll realistically happen (no autistic alt-history wish fulfillment shit nor seething brownskin fantasies):
>Cause of WW3
Modern governments are too bureaucratic and cowardly to go full bore so it'll be caused by a MASSIVE POWER VACUUM that forces them into action (most likely Russia collapsing into warlords drawing in NATO vs China.)
>S. America will be neutral
They gain nothing so they won't join.
>Africa
Some existing conflicts (like Sudan) might join the larger war. But other then that it'll be a side show of a side show.
>S Asia/Turkey
Will basically stay neutral occasionally seizing some small territory or bases for their own gain (claiming it's to help a side)
>Middle east
Expect bastardized clusterfuck alliances to form, like Israel+Azeris+Saudis vs Iran+Armenia+ISIS with endless indecisive wars that go nowhere.
>SEA
Will try to avoid the war at all costs. Although air/sea/island battles will happen all around them
>Central Asia
Will be neutral but basically Chinas bitch
>Eastern Europe
Poland/Finland/Ukraine will do 95% of the European theaters fighting
>West Europe
Will send minor token forces but will act like they're major contributors
>Anglo-sphere
95% of the fighting they do will be air/sea superiority and taking far flung Chinese/Russian islands/bases. Won't actually contribute that much tactically BUT will give NATO forces most their supplies money.
>China
Will funnel troops to prop up Russia/N. Korea. Essentially fighting a massive border war.
>S. Korea
Will be Verdun 2.0 static war that goes nowhere with horrendous losses.
>Japan
Like Europe will send token forces. N Korea will bomb the shit out of it to get cheap morale victories.
>Taiwan
China will attempt to blockade it. After US breaks the blockade China will bomb the shit out of it.
>Conclusion
It'll be static war with nothing much gained ending in ceasefire.
