Re: Message to all Chinese naval commanders.
That is what I was thinking. China is scared of the Donald. Already there are whispers of business moving factories back into the US from China. If China loses the world's largest economy, then it will be difficult to recover. Trump is a bully who pushed back twice as hard. China's action are clearly meant to show Trump how strong China is, it is meant to make Trump think twice.
If China starts an actual war with the US, it will be very bloody and never have a winner. Plus the economic damage would be catastrophic to China because they would certainly be embargoed. Trump is inexperienced, but even he is not stupid enough to start a war with a super power. If they start a cold war, the result would be the same. Sure, the US economy would suffer, but not forever. "Made in China" would be replaced by "Made in Vietnam" or "Made in Bangladesh". Donald is a bully AND he has all the trump cards. (no pun intended) China knows this, and they are scared.
