Scenarios where a truly hegemonic power/alliance rises up.

Hey all. Interested to see the forum's ideas on possible timelines where a true "hegemony" is established.

Some ROUGH criteria for hegemony that, while preferable, need not be on the nose:
1. GDP and/or Population at least 40% of the world
2. Ability to enact significant military action(invasion, airstrikes, other forms of bombardment) within 24 hours
3. Ability to make and live up to threats of military force against other countries
4. Significant or dominating influence in internation organizations greater than the UNSC

Personal thoughts:
1. China after a US-USSR nuclear exchange which leaves China intact
2. The US after a favorable Cuban Missile War/AANW-style World War 2
