I would suggest YOU familiarize yourself with the War Powers Resolution which gives the President 90 days within which to notify Congress after committing armed forces to military action "without an authorization of the use of military force or a declaration of war."<quoted text>
INTERNATIONAL Law as well as CONTITUTIONAL Law.
NO POTUS is above it!
I would further suggest you familiarize yourself with our duties under the United Nations Charter and NATO. When the Charter was signed, Congress authorized the President to commit armed forces as part of an international body. Besides, Obama's attempt to stitch together a multilateral alliance before turning to Congress doesn't violate a damn thing and only makes common sense.
