Any country with nukes and a disdain and distrust for both its own people and any country not like them is definitely a threat. Look back at history - the biggest threats were the ones that did terrible things to their own people.

We're talking about a country with 100k+ CCTVs monitoring their own people, loaded with anti-US and anti-South Korean propaganda, forbids internet usage, starves its people, has a top 5 military while being the size of Pennsylvania, and enslaves 200k+ of their own people falsely.

What evidence do you have that they are not a threat?
