When you use force, people get hurt, and when you kill people, their relatives don't like it. And usually war has some unanticipated consequences so it's something you shouldn't launch into, on the expectation that this is going to rally the nation. This is not like 'Friday Night Lights'.
George W. Bush has helped those who have most, hurt those who have least and ignored everyone in between.
Nothing is going to hurt this country - not bioweapons, not a nuclear weapon, not a terrorist strike - there is nothing that can hurt us if we stay united and move together and have a vision for moving to the future the right way.
