” I truly believe that in another ten years the Japanese navy will not be a match for the Chinese.”
That is as much up to the Japanese as the Chinese.
When WWII started they had the best Navy in the world. It was only because they could not continue to build that they lost the war. We cut them down to a few ships and they couldn’t build more.
We could apply the same principal to the USN. It’s up to us.
It isn’t how many ships they have now, its how many they can crank out in an emergency.
