As long as the U.S. remains a member of the organization, it's charter and binding resolutions of the Security Council ... are supreme law in the United States.

No, the Constitution is the supreme law of the U.S. unless you are arguing that we are not a sovereign nation which shoots the legs out from under your entire premise about violating the sanctity of a sovereign nation, ie. Iraq.

Where in the UN charter does it say that a member of the Security Council may not act without UN approval?
