Completely bypassing Congress on this issue, and potentially placing US military people in harm's way, should be an impeachable offense. This and any number of other egregious offenses he has committed over the last 2+ years. Could you imagine the lynch mobs outside the White House if W pulled one tenth the stunts Obama-lama-ding-dong has pulled? Mobs, torches, pitchforks, and a horse and lots of rope would have been awaiting him. But no, our affirmative action assclown gets a pass because he has the lamestream media running interference for him. No matter how bad he F's up, they will cover for him.
After dithering for weeks about Libya, Obama directed the use of military force, but never allowed Congress to debate the concerns most often expressed, and to consider a resolution. Given he began the whole process with the precondition that it would be a multi-lateral action; there was never a reason not to pursue discussions ending in parallel Congressional action. For Iraq, every initiative authorizing military force began with a U.N. resolution, was pursued with concurrent Congressional action and was confirmed by Congressional authorization.
