One could have said this about the U.S. and Germany in 1927.
I don't think war between the U.S. and China is likely, and I certainly hope it would never happen because no one would win that, but I don't think that argument has historic validity.

I've never heard Germany and the US being "inexorably intertwined" and find the comparison to China/US almost preposterous given the modern global economy and the feeder/lecher relationships we have now.
