Out of curiosity, what makes people think that there's any previous experience that prepares someone for the variety of major (sometimes life and death) decisions that a national leader is required to make? Have you watched the way being President has aged those who serve in that role? Nothing prepares a person for that, I think. And isn't the point of having a cabinet, chairman of the Joint Chief's, even a VP, ambassadors, even Congress, to bring many peoples' previous experience to bear in arriving at a final decision?
