The war of attrition involves bleeding out the empire with cost differentials. The MIC needs to provide more value for its weapons or the imperial outposts will become cost & geopolitically prohibitive.
The US has lost much stature among the global south. As the so called "adversaries" understand how to effectively drain imperial status & resources. The exceptionalism position does not help in light of regularly bombing civilians & making the world a more dangerous place by flooding weapons into conflicts.
And the quality of life of the people in the US & Europe is falling...fast.
