Wars are usually about logistics. In fact, logistics is pretty much always a factor. Sometimes a huge factor.

IMHO, I think China has been preparing for this for a while now. They are launching some very capable designs, and in large numbers. Are they a match for us? Probably not yet. And when combined with our allies, definitely not. But we should not minimize the threat. The want the South China Sea in its entirety, and they want Taiwan. They've been building the navy they need to get them.

Obama was too cautious, the convict just didn't care, and Biden at least is getting us some bases in the Philippines again (which will help logistics).

Here is perhaps a better source of information, though it doesn't paint a rosy picture, either.

Even if we build the ships, one needs to crew them. Last I knew, recruitment has been dropping for a decade or more. The military is not high on the list of career paths for younger generations. So that's another problem that would have to be addressed.
