Sure, he is partisan, but all people are.
Bush was brought up in the article to prove the point that Obama is basing his decisions under the status that he is the sole principle in deciding military action, as per Bush.
As for the Constitutional mertis of Iraq. Authorization of force, is not a product or use in the Constitution. Congress can declare War, that's it.
I knew it would finallY come out-—IT IS BUSH’s FAULT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I do not believe that a formal “Declaration of War” was ever issued in the Barbary pirate wars, either, but they were supported by the Congress.
I suspect that many of the Indian wars never had a formal declaration of war either. Please let me know if you find any.
