I don’t think it would be fun at all, especially if the Indians and Vietnamese can’t keep the Chinese at bay (highly plausible scenario). The Chinese navy is today strong enough to occupy all of the islands in the South China Sea (if US does not intervene). They are just itching for an excuse to do so. The Chinese also have high ground advantage against India around that area.
You don’t think the Chi-coms are in power as a result of the U.S. propping up their economy?
Stop our trade imbalance and they fall.
