I said Iran could have nuclear weapons, but North Korea should not. They are an insane rogue state that is very harsh and cruel. The United Nations should invade and take down the leader. It needs to become Democratic. The USA should finish what it started so many years ago.
Though South Korea's bellicose northern neighbor has been grappling for nuclear arms for decades, it does not fall to the rest of the international community to arm South Korea with nukes. Doing so would only escalate the struggle in that region, possibly leading to an arms race like the one between the USA and the USSR in the Cold War. Total worldwide disarmament is the better response to the danger South Korea faces.
