Not until there is the political will to accept millions of US losses. Our current engagements are a walk in the park compared to what "bringing regime change" to North Korea entail. I'd wager that there hasn't been another large populace so thoroughly brainwashed in modern history- Nazi Germany isn't even comparable to "the hermit kingdom."
I think you're totally wrong, there's no idealogical support for the regime there. The military support him because he makes them 1st class citizens and they know it's the only way they can eat. The civilians are just scared to death and trying to survive.
And there wouldn't be millions of US losses, we would never put ourselves in that situation. It would be relentless airstrikes aiming at disabling air defenses/artillery positions and decapitation of the regime. The problem would be mass civilian casualties in south korea.
Perhaps, however I think its hard to brainwash starving masses turning to cannibalism fleeing the country in thousands across the border to China. The German Nazi regime was well fed and well equipped.
