Former President Joseph P Kennedy Jr has passed away yesterday at the age of 96. According to the late President's memoirs, in 1944, he was to fly a PB4Y stuffed with explosives in a mission, and that PB4Y would explode and kill everyone aboard, but he was sick that day and was thus unable to carry out the mission. What if he boarded the PB4Y and died? Without a Kennedy Presidency (1961-69), how would US politics be different?
