Hypocrisy, thy name is the U.N

So, North Korea has launched yet more nuclear tests, to widespread international condemnation.
The United Nations Security Council - the permanent members of which, lest we forget, are all nations with nuclear weapons - have met to "unanimously condemn" North Korea's actions.
Do as I say and not as I do?
Maybe, as the guardians of the world's most powerful weapons, the Security Council members should just nuke North Korea. Then we could all live happily ever after, right?
Just wait for that Security Council resolution. Bet they'd have no problem whatsoever getting an agreement...
