I have always appreciated Harry Truman’s assessment of public service. He Said, “My choice early in life was either to be a piano player in a whorehouse or a politician. And to tell the truth, there’s hardly any difference.”
Many have given reasons for it, the one I find more credible was his displeasure with Truman for selling out Eastern Europe to Stalin.
Which is interesting, because Eisenhower didn't appreciate Patton's strong anti-Communist streak.
Then again, once you become a General, you have reached the pinnacle of politics in the military.
