"Eventually" here is doing a lot of heavy lifting. It's possible it will happen, of course, but is not within the realm of possible futures within the next ten to fifteen years.
For better or worse, the US is easily the most powerful force projection entity in world history. This was true before Russia was revealed to be badly broken and is more true now.
The superior ability of the US to project force in distant places does not inherently translate to the ability to beat China in its own backyard. The US has more and (much) better carriers, but China has, well, China, and a whole lot of missiles and planes there.
