SECTION 1. FINDINGS.

    Congress finds the following:
            (1) Article I, section 8 of the Constitution vests solely 
        in Congress the power to declare war.
            (2) The Constitution provides the President with the power 
        to act as Commander-in-Chief and with the limited power to 
        utilize the United States Armed Forces to ``repel sudden 
        attacks''.
            (3) The constitutional authority of Congress to declare 
        war, and the requirement that the President seek Congress' 
        express prior statutory authorization to deploy United States 
        Armed Forces are necessary to ensure the collective judgment of 
        both Congress and the executive branch in making the decision 
        to deploy United States Armed Forces abroad.
            (4) In a May 21, 2011, letter, President Obama notified 
        congressional leaders that United States military forces had 
        been deployed to Libya at his direction ``to assist an 
        international effort authorized by the United Nations Security 
        Council'', and that ``United Nations Security Council 
        Resolution 1973 authorized Member States, under Chapter VII of 
        the U.N. Charter, to take all necessary measures to protect 
        civilians and civilian populated areas under threat of attack 
        in Libya, including the establishment and enforcement of a `no-
        fly zone' in the airspace of Libya.''.
            (5) In a May 20, 2011, letter to congressional leaders, 
        President Obama wrote that he ``reported to the Congress that 
        the United States, pursuant to a request from the Arab League 
        and authorization by the United Nations Security Council, had 
        acted 2 days earlier to prevent a humanitarian catastrophe by 
        deploying U.S. forces to protect the people of Libya from the 
        Qaddafi regime.''.
            (6) Section 8(a)(2) of the War Powers Resolution 
        specifically states that the authority to introduce United 
        States Armed Forces into hostilities ``shall not be inferred . 
        . . from any treaty heretofore or hereafter ratified unless 
        such treaty is implemented by legislation specifically 
        authorizing the introduction of United States Armed Forces into 
        hostilities or into such situations and stating that it is 
        intended to constitute specific statutory authorization within 
        the meaning of this joint resolution.''.
            (7) Section 2(c) of the War Powers Resolution acknowledged 
        the constitutional powers of President as Commander-in-Chief to 
        introduce forces into hostilities or imminent hostilities as 
        ``exercised only pursuant to a declaration of war, specific 
        statutory authorization, or a national emergency created by 
        attack upon the United States, its territories or possessions, 
        or its armed forces.''.
            (8) The War Powers Resolution was passed by Congress over a 
        presidential veto in the aftermath of the Vietnam war, to 
        ensure that Congress had a direct role in the decision to 
        introduce United States Armed Forces into hostilities.
            (9) The introduction of United States Armed Forces into 
        hostilities authorized by the United Nations or any other 
        international body aside from the United States Congress is no 
        substitute for a congressional declaration of war or 
        authorization for the use of force.
