A ‘MUST READ”:

“Executive Agreements
In addition to treaties, which may not enter into force and become binding on the United States without the advice and consent of the Senate, there are other types of international agreements concluded by the executive branch and not submitted to the Senate. These are classified in the United States as executive agreements, not as treaties, a distinction that has only domestic significance. International law regards each mode of international agreement as binding, whatever its designation under domestic law. “
ONLY that which the UN can enforce is 'binding'. The UN can kiss my ass!
