The problem is not and has never been the military capability of the U.S. versus North Korea. We're talking about a country about the size of Ohio, with less than 10% of the U.S.'s population and 0.067% of its GDP.
The problems are:
- How many people is the U.S. prepared to allow to die in allied nations (South Korea, Japan) over hostility with North Korea?
- How many war crimes is the U.S. willing to commit in this conflict to bring it to and end?
- What happens to the planet when World War 3 starts with China and Russia opposing the U.S.?
Unfortunately, under the current administration, the answers to those questions are:
- Trump doesn't care.
- Trump doesn't care.
- Trump doesn't care.
So if the bombs start flying we're probably looking at nuclear holocaust.
