The language used conveys the wrong message in terms of 'your either with us or against us', but it does send the correct message that the paradigm that you are used to will be changing. I am sure there is room for dissension amongst allies that agree more often than not. It is the hangers on in the world that might get noticed. The U.N. was conceived to be something very different and has really turned into a socialist's social club that expects the U.S. to continue to fund it the way it has while accepting all the sniping from the peanut gallery. 

I wouldn't be surprised if the U.S. gave the U.N. its moving orders to reconvene elsewhere on this planet with a significant cut to U.S. funding.
