Agreed. I read a decent article about how Obama can learn from prior President's early mistakes, and they mentioned Kennedy and the Bay of Pigs foul up:
In the days following the abortive invasion, according to historian Richard Reeves, the president “was seen talking to himself, sometimes startling his men by interrupting conversations with lines like, ‘How could I have been so stupid?’”
Kennedy invited Eisenhower to confer with him after the fiasco in a show of national unity. The old general gave the young president a scolding, Reeves said. “Mr. President, how could you expect the world to believe we had nothing to do with it?”
As Kennedy told Bissell later, “In a parliamentary system, I would resign.” But the Constitution gives presidents a fixed four-year term. Early embarrassments, and even disasters must simply be endured.
