The debacle in Ukraine might give them pause. The window when US had any serious military advantage over China has already closed, and China will only continue to pull ahead going forward. On top of that, it's been exposed that the US military industry is not able to produce weapons to keep up with Russia, let alone China. And of course, a lot of the existing stockpiles were sent to Ukraine. It's quite likely that the war in Ukraine may have prevented a war with China because Biden admin overcommitted to it.
