The assessment predicts: "Tens or hundreds of thousands could become casualties" ... in the event of an all-out DRPK/(US+ROK) conflict. One factor to consider here is what happens if no conflict occurs? In that case, there are ... still likely tens of thousands of civilian deaths happening as the status quo in North Korean labor camps[1].

"Allowing the regime to continue to exist" is a backwards way of looking at things that serves to legitimate invasions. The US is a superpower, but that doesn't mean that other nation-states exist because we deign to suffer their existence—that's a very colonialist way of looking at the world.

Regardless, the colonial past of Western powers is not relevant here. I am not suggesting a policy of Imperialism. I am just pointing out that North Korea's very existence comes with a serious cost in human life. This might be something we should at least factor in when weighing the heavy costs of destroying the Kim regime.
