War should be by assassination of leaders

There's far too much in the way of war and not enough in the way of assassination. If Hitler had been shot... If Saddam had been shot... If Joseph Kony could be shot... The world would be a better place. The United Nations should declare that any country formerly with a legal right to wage war, in future will only be allowed to assassinate its enemies' leaders. In effect war will be redefined as a battle to the death between leaders. Any leader who tried to launch an old-fashioned war would be eliminated. It's a safe bet there wouldn't be any wars if the leaders had to put themselves in the firing line. It's only our lives they don't value.
