The one thing you didn't count on are our countermeasures. Should it come to that, North Korea's ICBM will never make it to US soil, but they will be soiling their pants when we retaliate. Of course that won't do much good either because by irradiating the far east that will create even more enemies for the US and if they, particularly China decide to retaliate we ( the US ) are totally f**ked, with absolutely no loving.
Money makes for a powerful ally, China going against the U.S. cuts themselves off from a major financial income
And what happens when they realize that the dollar only represents our governments promise to pay just so much for it ? Fiat currency is worth about as much as it's namesake in vehicles.... Not a whole lot.
US and UK blame North Korea for WannaCry The US and UK governments have said North Korea was responsible for the WannaCry malware attack affecting hospitals, businesses and banks across the world earlier this year.
