Yeah, ok. I just showed you written law that specifically says that Congressional approval is necessary and your response is 'no it isn't' and 'New was wrong'. Great argument there.
It cannot get any clearer than the law I just showed you. I don't know if you're choosing not to see it, or if you really can't make the distinction between serving under US law and serving under UN law. Regardless of how you think US soldiers should be allowed to be dispatched, the law says what it says. New was absolutely right.
No, what you showed me was one section of a piece of legislation that you claim showed that it required congressional approval. What I said was that the courts obviously disagree with your interpretation and have declined to intervene in the case. You can make any interpretation you want, I'll go along with all the courts that have examined the matter and determined that New's case doesn't hold water, and that the verdict he received was fair and proper.
