but i think it's because presidents take it on themselveses to get so involved with the electric chur, so involved with the laws that they need more and more people to assist them. i don't think it raises any constitutional difficulty. libya, i think is a demonstration in the last few years president presidents who actually have been trying to bind themselves to reduce the kind of vigorous constitutional presidency that should operate a national security and foreign affairs, for example, what struck me about libya was the claim that libya was not a war. which i think would have surprised mr. gadhafi because we were trying to kill him during that conflict. but we delay it it for two to three weeks so we could get united nations approval. the administration thought it was more important to get approval from united nations than from the congress. i thought that was a remarkable thing -- tie tarrant county fate of our national policy to an organization that is not even part of our political system. thanks very much. >> thank you very much, i sal lewd barbara, michael, lon, gabe for arguin
