The US’s biggest problem right now appears to be an inability to build. The U.S. is the world’s biggest arms seller in terms of revenue and yet it seems it’s incapable of ramping up ammunition production to meet the needs of the Ukrainian military, which would be a fraction of the needs of what a war that involved the U.S. fighting a symmetric power like China or Russia, as opposed to cave dwellers from the 19th century would require. Add to that the general inability for the U.S. across both private and public sectors to do anything cheaply which means even a poorer nation might still have greater resource capacity than the U.S. So even though China's economy, contrary to expectations even a year ago, might now never grow as large as the US’s economy in dollar terms, it would still have greater capacity because it’s able to wrangle out a lot more output for every dollar than the U.S. is. Finally, while Russia’s invasion of Ukraine thoroughly discredited the Russian military, it’s also exposed the US’s lack of preparedness for the next version of war which will be heavily driven by drones and the like. Unfortunately the U.S. is relying on heavy expensive weaponry and doesn’t seem to have a great counter for inexpensive weaponry deployed in mass. So, Russia can fire large number of cheap Iranian drones at Ukraine, but Ukraine has to spend a million dollars worth of defensive weaponry to take down 100k worth of those drones, an economic difference which would not be sustainable in a larger war.
