I don't understand it either. He thought nothing of joking about nuking the Russians and fighting a "limited nuclear war" over Europe (evidently not understanding that the Europeans might have been just a wee bit pissed off about that). I was in high school during part of the time he was president, and my social studies teacher referred to him as "Ronnie Ray-Gun." When he survived his assassination attempt, so help me, I was disappointed - because he was such a WARMONGER.
Sure, we've got a bunch of warmongers now, Canada's Prime Minister among them. But there's a difference between the kind of war that's been going on for the past 10 years and a nuclear war.
