The book "Then Everything Changed," by Jeff Greenfield has a very plausible and interesting scenario describing what would happen if that attempt succeeded. I can tell you, after reading that section of the book, I felt very uneasy about what could've happened, and very greatful that that lone extremist failed. Up until now, I had no idea that there was an attempt on JFK before he entered office. I did wish that Greenfield expanded his RFK Scenario a bit, since I was dying for another detailed take on an RFK Presidency after reading A Disturbance of Fate and RogueBeaver's The Impossible Dream. Still, I'm a bit peeved that in Greenfield's timeline, MASH isn't a success and neither is Patton, since those films were classics, with the former establishing Robert Altman as a good director. I will not say anything about Gerald R. Ford getting a second term, or Gary Hart becoming president, and being "caught in-flagrante" by, none other than, Deputy Chief of Staff Hillary Clinton. I am curious, was there really an assassination attempt on the Ayatollah in 1978?
