Yes the risks of fighting N Korea are great. And they are that much greater when N Korea is a nuclear power. I think a lot of people really are forgetting what N Korea is. How fanatical, militaristic, corrupt. That they caused a major war with the United States. That they hate this country. N Korea might want S Korea, but their real hatred is for the US and Japan. And the stronger they become, someday they will launch a real trade wind in our direction. Maybe not this year or this decade, but someday when we are weaker and they are stronger.
How long did it take us to test a nuke and then use two of them? Capiche?
