I agree with the idea that the ability to forgive and forget the bitter times of the past is a great attribute and talent for a leader to have, but this alone does not create a leader. Many sympathetic and shy people are very good at doing this, I believe, even though they are not leaders. I don't see much evidence as to why the U2 singer makes a good world leader. He certainly is an interesting soul considering the international presence he has, but what about his works or personality make him a world leader? I was not able to draw out a reason for this from the video.
