After years of endless military threats against Russia—remember CIA deputy director Mike Morell saying on TV (Charlie Rose show) that the US should start killing Russians to give them a message, and Army Chief of Staff Mark Milley threatening "We'll beat you harder than you have ever been beaten before"—now the US Treasury Secretary Steven Mnuchin threatens China. If China doesn't abide by Washington's new sanctions on North Korea, Mnuchin said the US "will put additional sanctions on them [China] and prevent them from accessing the US and international dollar system."
Here is the broke US government $20 trillion in public debt, having to print money with which to buy its own bonds, threatening the second largest economy in the world, an economy on purchasing power parity terms that is larger than the US economy.
Take a moment to think about Mnuchin's threat to China. How many US firms are located in China? It is not only Apple and Nike. Would sanctions on China mean that the US firms could not sell their Chinese made products in the US or anywhere outside China? Do you think the global US corporations would stand for this?
