We would be fighting on the other side of Earth.
The Chinese?
At least in the beginning, they would be fighting more or less in their own backyard.
That said, the Chi-coms gotta lil more maturing to do before sinking a carrier. That would unleash a hell storm on China. Their lil man made islands would be gone. Any ship not out to sea would be sank. It would be ugly...for everyone involved, but particularly China.
