Winston Churchill, one of the greatest men of the 20th Century, is a good example of a great man with flaws.
Full disclosure: I embrace his flaws, because it makes him so much more interesting...:) Smokes...drinks...swears...eats bad food...is occasionally stubborn, stupid, dense, and wrong. In other words...he is like many of us!
Winston Churchill is my favorite person from the 20th Century.
