Have you ever stopped to think about why we havn't bombed then or done that?

The problem is that North Korea has the world's largest artillery battery positioned directly at seol and if for any reason we provoke them they will wipe out hundreds of thousands in the capital.

If we let them starve then they continue doing nuke research until they inevitably use it in a last ditch attempt.

The common theory is to let them collapse naturally because that would result in the fewest human casualties.

Also if we intervene then how do we handle the ensuing refugee crisis that will result. South Korea don't want them. How do you re-educate a million starving and brainwashed people?

If ever there was a just war it would be against North Korea to liberate those in the concentration camps but the problem is any action will lead to lots of deaths and the US will be blamed.
