What else can you expect from somebody who was the head of a small country for nine big long years suddenly having to leave everything, uncertain of future, no more guns, no more funs, no face saving, to do while giving his last speech. He knows for certain that he would not get another opportunity to talk on TV (atleast as the President) and tears and sobs are natural. He may be a soldier of army but by birth he too is a human being. And when nobody else pities him in the entire world, atleast he has to pity himself.
