Through the processes of committing to Aid programmes and the UN, the US has incorporated a certain amount of internationalism into its legal system. The power given to Congress by the War Powers Act must be balanced against the fact that the executive retains control over US foreign policy.  Secondly, a UN resolution that allowed the use of air power by countries to protect civilians.1 This means that fears of conflict escalation are unfounded and given that the UN resolution exists, the war powers act is not weakened significantly as it would still mandate a UN resolution to prevent conflict escalation.  Even if the U.S. government sought regime change however, it has moral legitimacy in doing so because of the demand for such changes from a large number of members of the international community.2  Lynch, Colum, ‘Security Council passes resolution authorizing military intervention in Libya’, Turtle Bay Foreign Policy, 17 March 2011,  “War Powers Act.” Cornell University Law School.
