I don't see anything nasty about this. Could you elaborate? It seems pretty straightforward and balanced to me. (There's also nothing particularly letterish about it.)
It's a reference from Team America where Hans Blix tells Kim Jong-Il that if he doesn't stop making nuclear weapons they are going to send him a "nasty, nasty letter". What I mean is that this resolution does not nothing but tell the countries we don't like them. I introduced my measure because it is effective. Its like asking whether a parent who tells a toddler to stop doing something is more effect than the parent who teaches them there are reprecussions for their actions.
