John F. Kennedy was the last good President, the last one to actually care about America, as for Johnson, Nixon, Ford, Carter, Reagan, Bush, Clinton, Bush, Obama they were bad presidents.
I would say Ronald Regan, he did more for this country then any other president. The next best I would say was Bill Clinton I wish he was still in office.
Except for his very active sexual appetite while in office, I would honor Bill Clinton as one of the most noteworthy presidents in the history. Coincidentally, the other president I admired was also another macho guy -- JFK! As for Republicans, I am singling out Ronald Reagan.
The Dalai Llama is the best world leader. Franklin D Roosevelt did a lot for the USA which is why he was elected to three terms. If we had done the same things now that they did then, our crisis wouldn't be as bad as it is.
I would have to say John F. Kennedy, also. Not only did he start the space program, but he also, like MXrider said, cared about the the people and the environment in the United States!
