This almost belongs in the Geopolitics thread, but the immediate connection is the French warmongering against Russia. History Legends did a fantastic video going into the French struggles in Africa and how Russia and China are winning on the diplomatic front, while the US and France are (literally) retreating.
While the UK lost basically ALL its overseas possessions (they still control the Falklands, Gibraltar and a few others), France has held on to many colonies, even if it has given them de jure "independence." It still controls many overseas possessions, and HL goes into detail on the history in New Caledonia, Burkina Faso, Niger, and others. France's history with Algeria is one that has always baffled me, as it seems to have caused so many negatives for the French, and I can't see why the French leaders pursued it for so long. But I would say that France still has the most effective system of colonization today (US gives them a run for the money).
Anyway, the outsized wealth of US / Western Europe is due in large part to economic control over global assets. That was curtailed heavily in the 1960s, with the western countries opting for a more "Confessions of an Economic Hitman" type model of indirect and financial control as they gave up direct control and decolonized, granting the nations independence.
That new system is now being upended as well. And due to the idiotic moves by the US, the ability to use the dollar and the IMF to force the hand of these foreign nations is heavily weakened.
New Caledonia has over 10% of the world's nickel reserves, vital for stainless steel production, among other uses.
US / French influence in this region will be gone within a decade (with perhaps a holdout or two--the US has actually been able to reverse things in the Philippines which is now falling back into being a tool of America), and it is very certain that the Chinese belt and road strategy, and/or the Russian mutual assistance and traditional diplomatic models will succeed. (In contrast the head of NATO Jan Stoltenberg has stated that one goal of NATO is spreading gayness, which Africans are not so keen on).
Putin has made it very clear that if the west keeps arming Ukraine, he can arm places like New Caledonia. I honestly think the American leaders, at least, are too stupid to understand the threat (he did not mention New Caledonia by name, and I think they won't "get it" until they see the Caledonians using the weapons and physically pushing out the French!)
Finally this probably deserves its own thread but Macron has called for elections, and many outlets fear he will be ousted, replaced by a "far right" candidate.
There is a good chance that we may finally see things start to change on the global level. I suppose one could say that already happened with the US losses in the mideast wars, but the US also lost Vietnam, so nothing new there. This is going to fundamentally change the global economic system, and is another hit accelerating the decline of the petrodollar.
