America is more than ready, considering how much we spend on the military. This article is a few years old, and definitely sensationalist, but is still an interesting read-
And on top of that, the US Army just started deploying robotic troop carriers, and is finishing up remote combat vehicles for the front lines so that first contact isn’t with soldiers. Yes, we’re going to have killer robots on the front line. And soon.
The US military is routinely overestimated in its capabilities. How much it spends is not a point of strength. China and other countries produce their equipment at cost, getting 1 dollar of value for every dollar spent. The US with its for profit system snd regulatory capture by the Military Industrial Complex, instead massively overpays for everything from missiles to spoons.
US also spends a lot on healthcare, just because you spend a lot of money on something doesn’t mean you produce good results. Not to mention that cost of production in US is an order of magnitude higher than in Russia or China
