What about the UN? Wasn’t this a UN Mission...we are such wusses.
Perhaps we can obtain a UN resolution condemning the pirates' actions. No doubt, that would fill them with unimaginable terror.
Or, if "condemn" is just too strong of a word for the niceties of diplomatese and UN-speak, we could at least seek a resolution expressing a moderate degree of "concern." (Provided, of course, that Russia and China don't veto it in the Security Council.)
Or...well, something. Anything.
