War with North Korea will a catastrophe. Perhaps the deadliest war of our times. And if it happens, it's China's fault.

That's according to Asian analyst Gordon Chang.

Chang, an Asian analyst and the author of "Nuclear Showdown: North Korea Takes On The World", joined the Tom Shillue Show on Wednesday to explain how President Donald Trump could both avoid a war with North Korea and stop China, the rogue country's only ally, from propping up its government,

He even gave the President some twitter advice, suggesting Trump call out China for supplying North Korea's military.
