The only problem with that premise is that there are no "good men". The US certainly doesn't qualify. Take the illegal invasion and occupation of Iraq based on deliberate lies and deceit, for instance. Or if you prefer, the CIA overthrow of the democratically elected government of Iran. There are countless other examples, but I won't bore you with details. If you really want to crusade for "good", it would seem to me to be a good idea to fix your own "goodness problems" first.
Got any actual proof to support that allegation? I would think a real "maniac" would have attacked SK long ago, instead of simply posturing and saber-rattling whenever he and his country feel threatened by the same "good guys" who have been deliberately harassing them ever since GWB labelled them part of "the Axis of Evil" after 9/11.
There is not doubt that NK is a repressive totalitarian goverment. But there are dozens of right-wing ones in the world today that either go completely unnoticed or are actually our "allies". But the Cold war taught us that left-wing ones are always vile while right-wing ones are really not all that bad, since "good men" don't seem too preoccupied with those.
It certainly wasn't "other people's problem" until GWB started openly harassing them. NK/SK relations had steadily improved until he started posturing against them, thereby annoying the hell out of the leaders and people of SK who are actually threatened by such rhetoric.
I guess you are forgetting all those years when SK was a barbaric totalitarian government no better than NK was. Yet they still received the undying admiration and support of the US government long before they finally decided to give their own people the right to vote.
This thread is yet another classic example of right-wing extremism at work. A NK newspaper writes a commentary that nuclear weapons may now be used offensively if they are provoked enough. Since all media is controlled in NK, everybody simply assumes this is now the official government position, which it may or may not be. And now, the far right is trying to use it as a justification to wipe them off the face of the earth, even though the US officially threatened nuclear war itself many times in the past.
I'd say NK has likely accomplished their goal. While doing nothing officially, the US will think twice before advocating harsh embargoes that will only cause the people of NK to further starve, just as the people in Iraq did after the first gulf war. And then they will point at all the starving people which they directly helped cause, and state "Look how evil NK is!" After all, it worked with Iraq, and as it continues to work with Cuba...
