Bush Administration's reputation may lead to disaster?

Iraq invaded without solid proof of WMD's...and never found any. Iran enriches Uranium, does everything it can to prove they are not trying to make a weapon, USA not buying it. North Korea actually builds a bomb, so they fear an attack as well, something they claim to have done to stave off an attack. Now Bush has said he won't attack North Korea. Is our reputation as a nation in the gutter now or what? Is the Iraq situation now lead to what could become a full-scale war in a place that we are not fully prepared to defend? I gotta tell ya, I'm scared for us all.
