Dubya is an idiot. I saw him in person in 2000 when he was at an event celebrating the first relicensing of a nuclear power plant. He tried to tell a joke about how he did not have to be smart because of all the smart people around him were smart. The joke fell flat, imo because many could see in the moment, he was literally not smart, I had the same impression.
That one statement set us back more than 25 years in properly addressing the threat of Islam.
