The Libya intervention lacks sufficient international authority  Firstly, the UN intervention in Libya wrongly rests on NATO authority. The use of NATO to circumvent congressional approval in this situation violates the initial agreement regarding the participation of the U.S. in NATO that was ratified by congress. As such, even if the U.S. is legitimate in going to war and the circumvention of war powers can be justified, the circumvention using NATO cannot.  Secondly, the use of UN approval to circumvent congress means that the UN charter and the ideals of the UN have been placed by the government at a higher level of value than of the US constitution. If this is the case then the government has undermined the validity of the US constitution and through doing that has undermined all laws within the U.S. which is harmful should the U.S. wish to project power in a way that is contrary to the UN’s wishes.1  Editorial: “Obama’s illegal war” The Washington Times. 18/03/2011
