I understand the horrific choices that have to be made when you are in charge. We can only judge by the history we have, but if Roosevelt had not positioned us to join the war effort with troops, the world would undoubtedly be far different. As far as JFK is concerned, I understand what he was trying to do. He took a risk and failed. It may have turned out differently for him, but he fell on the bad side of grace and paid for it. If he had succeeded he would have been rewarded, he failed and it turned out poorly, but he didn't quit and wallow. He recovered. There are mistakes in war, i understand that. Sometimes you take a risk and it pays off, other times you fail. It is the nature of war to be unpredictable. Folks have played it safe and by the book and had catastrophic failures, but our greatest heroes took a big risk and came out on the side of grace. He wan't a hero because he failed, it was that he persevered and was able to be rescued with his crew.
