Apples and oranges... While North Korea has been a threat since 1953, tell me how many Americans have been killed as a result of that regime since? Now, how many Americans have been killed as the direct result of Iranian-sponsored terrorism since 1979? If you think Iran is less likely to use nukes (if they get them) than North Korea, please elaborate why. Yeah, North Korea is somewhat unpredictable; but I feel they are far likely to go full on stupid unless they feel the regime is threatened versus Iran who would use them (especially against Israel) for far less justifiable reasons. Iran’s leadership blends religious ideology with state strategy, which could make its decision-making less purely deterrence-based than a typical state. North Korea’s primary goal is widely viewed as regime survival above all else. Iran has a long track record of using proxies (Hezbollah, militias, etc.) that creates a scenario where escalation could occur indirectly or ambiguously. Iran operates in a densely contested region (Middle East) with multiple adversaries, frequent conflict and short missile flight times which increases the chance of miscalculation, rapid escalation and pressure to act quickly in crisis. This recent conflict with the US, and the fact that several Middle East countries are siding with the US on it, has clarified who are their allies and who are their adversaries. Overall, Iran's ideology, proxy conflict and regional instability far more increase the risk!
