Another extensive rounding upon facts and figures to create a quality of analysis rarely seen, at least in part because todays' intellectuals are mostly stuck in silos labelled, history, geography, politics etc etc.
I agree with much of your analysis but I think the paragraph above, shows how you are skirting around the issue of white entitlement and lust to maintain world domination at any cost...
It is a misnomer, to say the least, to describe 'the global war that's raging g right now', is due to 'a Climate Crisis'.
No, it's due to the arrogance of the Euro-american leaders and their brainwashed populations who wish to continue to monopolise the earth's resources, acting like remorseless psychopaths who have already devastated massive regions of the planet and already caused mass starvation - for which they still shirk responsibility.
China is not a war-mongering nation whose wealth is derived form centuries of invasions and enslavement. There could have been a smooth transition as occurred between Britain and the USA, as you reference - but for the maniacal racism of the Europeans and their settler states, causing misery and jeopardising the survival of everyone on the altar of their greed -filled hubris and vicious double standards.
