Your challenge, should you choose to accept it, is to craft a world wherein both World Wars are averted, but the world is still largely as peaceful as it is in the modern day of OTL.
You may have Cold War-esque tensions between (blocs of) great (or not so great) powers (even to the modern day), as well as regional conflicts comparable in scale to the Franco-Prussian War, Polish-Soviet War, Korean War, Arab-Israeli Wars, Iran-Iraq War, or even the Gulf War, but prolonged total wars between great powers are prohibited.
In general, you should try to preserve as many of the pre-WWI multi-national/ethnic empires as possible, though the same directive does not apply to colonial possessions.
Bonus points will be awarded for scenarios which feature UN-like, EU-like, OECD-like, or NATO-like organizations, and extra bonus points will be awarded for scenarios in which the world as of 2016 is not in a state of Cold War-like tensions.
