Well, give or take some hours and the International Date Line. But the Japanese surrender did occur on the 15th of August for most of the combatants (the surrender documentation was signed on 2 September in Tokyo Bay).
And it has been 75 years since the last Great Power War. 75 years.
Think about that for a minute. Throughout history, kings and khans and emperors and pharaohs conducted warfare pretty much at the drop of a hat (any hat). The only comparable length of time in European history is from 1815-1870, and you had the Crimean War (involving Britain, France and Russia, albeit on a limited scale) during that time. But read history, and war has been fairly common on the European continent.
I mention Europe because I define “Great Power War” as the ability to fight a war on more than one front and in large tracts of area. And until recently, with Japan in WWII and China today, Europe was where most of the "Great Powers’ resided (I place Ottoman Turkey and Russia in Europe, which seem fair given their history).
It hasn’t been peaceful, those 75 years. Korea, Vietnam, Congo, Falklands, Bosnia, Kosovo, Iran-Iraq…and many others. But the real killing power resides in the Great Powers (more now than ever) and they have not engaged each other since the Japanese surrender. Not that they are peaceniks, mind you…but with the advent of Atomic weapons, they have all learned that “the only winning move is not to play”.
So yeah, politics is a cesspool and racial and economic divisions here and elsewhere can cause issues, but when you reflect that WWII killed nearly a million people A MONTH for it’s last several years, maybe a world without Great Powers at war is not totally a bad thing…because I am of the inalterable belief that if Nuclear weapons had never been invented, WWIII (and probably IV) would have already occured on our timeline, to what disastrous ends one can imagine for themselves.
So…75 years without a major war. Shall we try for 100?
