Even Bush gave congress the right to oppose his going to war against Iraq; the Democrats gave Bush their stamp of approval.
Going to war in Iraq was debated for months even though Bush's war against Iraq was opposed by the majority of the American people.
Apparently Obama learned something from Bush about the American public's disdain for imperialist wars and he knew that if going to war with Libya was discussed it would be the end of his political career; so, without any public discussion or debate he just evaded the War Powers Act and the United States Constitution and went to war without even pretending to respect the laws of the land or the American people and shoots off over 150 Tomahawk Cruise missiles at $1.8 million dollars a pop like a kid playing with firecrackers on the Fourth of July as he talks about "fiscal responsibility."
