There is no point in asking them to play by the rules because their rivals know that they can't enforce the rules any longer, US foreign policy has made it almost mandatory for rogue nations to seek these weapons and failure in post war Iraq has given them the confidence to ignore convention to do it.

Singling out these countries and making threats is only effective if those countries believe the threat is credible(and it is clear they do not), India, Pakistan and Israel have all developed nuclear weapons with impunity, there is no reason to believe that Iran, Syria and North Korea will not do the same.
