If US hegemony ended today, it would mean immediate war […] The US is far and away the most powerful military in the world, and without the threat of the US military intervening on behalf of its allies, those conflicts are nowhere near as one-sided as they are today. […]
See, the problem here is that all the potential apocalyptic conflicts between american allies and other nations are contingent on the existence of american foreign meddling in the first place. The global conditions of multipolarity between now and WW1 are different. The reason for animosity between america’s allies and their neighbors is that the neocolonial western powers, headed by america, are using these allies as pawns, puppets to further their own interests within these regions against its enemies. It would instead be more accurate to say that if america’s enemies were weaker militarily and economically, america would be able to swoop in and destroy their people via a combination of hard and soft power using its allies as forward operating bases. I am not saying that the enemies of america are perfect nations, however, in the absence of american meddling, they have been shown to pursue more peaceful and mutually beneficial international relations with neutral nations, as opposed to outright warfare and economic genocide, as america does.
As such, if there is no america, then there would be no threat of slaughter for its enemies through its allies, and therefore there would be no more reason for the sort of animosity that could spiral into a nuclear war. The enemies of america, due to their position, are generally intelligent geopolitically, and do not possess the historical legacy of being colonial empires. If america truly fell, then they won’t start wars against a now nonexistent enemy for no good reason.
Whatever you want to say about the crimes against humanity committed in the maintenance of US hegemony, I will agree with you, but that doesn’t mean for a second that the alternative is better.
This is a common argument for a neoliberal status quo: “Well sure we know global regime X is shit and kills millions of people per year, but hey, all these strawman alternatives are bad so in the end, There Is No Alternative.” It’s been overused by conservative politicians to the point that its a slogan: TINA. However, we must realize that there are multiple alternatives, including the building of a better world.
Be careful what you wish for and all that.
Its going to collapse anyways over the next century or so, we do not need to wish for anything.
