It's neither. The US is in an incredibly bad position right now because of three decades of under investment. After closing too many public yards after the cold war now the USN is barely able to keep up with regular maintenance during peace time of it's vessel's, let alone during a war. The average age of most American vessels is greater than that of their sailors. All while they're asked to face down the PLAN which now outnumbers them and is newer.
