I may be showing an age bias here since I am 26 and was in elementary school when Reagan was President, but George W. Bush, may even be eclipsing Reagan in terms of the effect that he will have on history.
Reagan was the greatest President of the 20th Century, but I think Bush after these next 4 years may have his mentor beat. As inspiring and courageous as Reagan was, I dont think Bush would have retreated from Lebanon. Maybe I am just showing a generational bias. If I am let me know. As far as I can tell Bush is made of steel. He doesn't break, fold, or bend!
Without Ronald Reagan, George W. Bush would never have been elected President. Oh my...can you imagine a world in which Jimmy Carter was re-elected in 1980...and Walter Mondale was elected President in 1984.... AAAAAAH!
