 So this hesitancy in this, maybe in some cases, just fear in Seoul, I think is well-founded. I also think that America has a history of spilling blood in the Korean Peninsula in the 1950s when it mattered most. We've demonstrated that we can be there when the moment arrives. The question, though, is can we make sure that moment never comes and that deterrence does not fail? And I think that's the big question right now.
