Now The World Wars NEVER happen for some reason (You can make up some scenarios!) What would Europe, Africa, Asia, South and North America Look like? What would Russia become? Discuses it with me OR your selves :3
It probably depends why there wasn't world wars. WW1 was pretty unavoidable.
But try think 20th century without WWs.
Europe:
German Empire survives and develops as constitutional monarchy. Austro-Hungary probably still collapses due internal troubles. Ireland might remain as part of UK or then not. Iceland is still part of Denmark. Russian Empire probably collapses but it is very different than in OTL.
Americas
United States remain as isolationist nation much longer and its civil right movement might delay couple decades. Probably USA can held hegemony in Central America longer and Cuba is longer under USA's thumb. British colonies are still colonies.
Africa
Colonialism last longer and on 2016 there is fewer independent nations when there is much smalle decolonialist movement.
Middle East
Ottoman Empire might be still around and we have much more peaceful ME. Without Israel and European colonialism extremist Islamic movement is much smaller.
Southern Asia
Decolonisation of India happen still but it is different event.
East Asia
Hard to say but probably there is much stronger Japan.
South East Asia
Decolonisation still happens.
Australia and Pacific
Europeans keep still all Pacific islands and Australia is probably pretty same as OTL.
