If you look at Russia's performance where there has been water in the way it's been kind of terrible. Their navy in the Black Sea kept getting hit by missiles and naval drones and has had to go hide and they've been largely unable to cross the Dnieper river.

The US would only need to bring an aircraft carrier to the general area and then could base aircraft in Taiwan. Even if the Chinese military was stronger than the US it'd be a difficult task for them.
