I recall someone (name escapes me at the moment) defining WW3 as ignition in 5 flashpoints between belligerent groupings:
- Eastern Africa esp. Sudan, which we all nearly universally ignore
- Israel Iran
- Russia and a neighbor which we know today is Ukraine
- Pakistan Afghanistan India
- China Taiwan Plus Plus
Attributes that distinguish WW3 from previous world wars were IIRC: Contained conflagration, short targeted exchanges, probability of contamination low, material possibility of nuclear escalation. Case in point: North Korea developed nukes without being invaded, and now that they have nukes, other countries are watching and seeing that NK won't be invaded. What lesson do those other countries draw? And what of a world in which many potential belligerents hold nukes? Hiroshima weeps.
I'd like to add an important attribute here: The revolution will be live-streamed, more-or-less. And essentially none of us will know the truth, even the reasons. I predict this fact will not distress many people, such is the state of humanity.
So to the 7 or so decades of stability we and our ancestors enjoyed, here's looking at you, going down me. But Brettonwoods serves the present the least of any time since its creation. Case in point, w.r.t. eastern Africa, the geopolitical bounds of those ~4 countries seems likely meld to a degree. If we are indeed heading into WW3, I expect the world map to be redrawn afterwards, and the only lessons learned is how to win better in future.
And if we are, while disgruntled old geriatrics go at each others throats via their youthful proxies, I greatly prefer the nukes rust in peace.
Reminds me of Blaise Pascal's quote: 'All human evil comes from a single cause, man's inability to sit still in a room.' Aspiration, you gotta take care man, it just might kill ya.
