There have been quite a few in my lifetime: FDR, who ran a world war from a wheel chair and Harry S Truman, who ended the war with a bang. Eisenhower came back from the war and warned of the military-industrial that empowered him. JFK faced down the USSR in Cuba.
That’s not all of the courageous ones by a long shot, but, that brings us to LBJ. In discussing the wily old head of the FBI, J. Edgar Hoover, a man who had all of the Washington elite in fear – LBJ said “I’d rather have him inside the tent pissing out than outside the tent pissing in.”
