You also assume that with almost no naval tradition, that China would be able to build a fleet superior to that of the combined US, Japanese, Taiwanese and South Korean fleets? That would be quite a feat. Historically unprecedented, to say the least.
The Buchananite calls for no free trade (a.k.a the Supreme Corporate Welfare - No Foreign Competition & Fat Profits) are interesting, too. Somehow, letting American consumers buy cheaper goods, thereby leaving them with more money to save and invest in America's future, makes us a poorer country. Interesting. I wouldn't suppose you heard of a fellow named David Ricardo?
