Everyone who participated in the conflict, yes. The IRA and UDA/UFF were both unquestionably guilty of committing atrocities during the Troubles. The North Korean situation is much different -- one-sided persecution of the masses by the ruling class. The GDR would perhaps be a better analogy. It's hard to envision an end to this situation that does not involve Kim Jong Un and thousands of others on the gallows, which is why I absolutely do not believe in the sincerity of these overtures.
