The UN was supposed to be our last, best hope for peace...It failed.
But something else succeeded: the military might of the USA. That is the best hope for peace in the world and it is working.
We ended Nazi Germany and Facist Japan. We ended the the Soviet Evil Empire. And we will defeat the Islamofacist threat.
Of course. If it had succeeded, all the UNweenies would be out of jobs. There are only so many openings for left-orbit politicians and TV talking heads selling bad books.
