@Zardoz,
I can't see China doing that.
Chinese soft power has made Canada, Europe and other Western powers view the country favourably.
A UK chamber of commerce was quizzed on the BBC. When asked if China was a more reliable trade partner than Trump's America he replied that it's been more reliable for the last decade.
Trump has accelerated the rest of the World's reluctance to trade with America. China is riding high, they're doing incredibly well without the need for military action.
And if China was to start fighting, it wouldn't be in the Middle East and Iran, it will be Taiwan.
