A recent commentary in BusinessWeek (Registration Required) provided the most straightfoward summation of why not to vote for Bush in 2004.
The domino effect of removing Saddam has not occurred. Getting rid of him was supposed to clear the way for a new road map for peace between Israelis and Palestinians. It hasn’t. It was supposed to scare North Korea into freezing its program of building nuclear weapons. It hasn’t. It was supposed to curb terrorism in the region. It clearly has had the opposite effect: Before the war, Iraq was not a hotbed of terrorism. Postwar, it is. We created what we said we wanted to prevent.
