I agree that this is a step in the right direction, but this won't look to good for others. People who agree with the Iraq war may see this as "backing down" from a potential threat. Others who oppose the war will see this as pure hypocrisy. Why lift sanctions on one country, but invade a country who only rumored to have WMDs.
Korea has nukes and displays them.
