The New Red Dawn movie looks more and more likely, all it would take would be the North Koreans getting a lot of under the table help from China and use the North Korean invasion of the USA as cover to take back Taiwan....
There are very few countries that can project power across the oceans and North Korea is definitely not one of them. China is not one either..... for the moment.
I believe the Chinese are tiring rapidly with Chia Jr. and things appear to be getting worse. Dear Leader II and North Korea are becoming a major embarrassment to the Chinese government.
China wants trade and you have to think they would like a reformed North that would benefit them instead of the train wreck in the crosshairs of the UN that costs them money.
