Sir: After almost 10 years, two wars and countless bomb explosions, Osama Bin Laden, terrorist leader of al Qaeda has been killed by American forces in Pakistan. He was the needle in the haystack for whom coalition forces were conducting worldwide searches since 2001, when al Qaeda brought down the Twin Towers. With the death of Osama Bin Laden, this 10-year search has finally come to an end. Since 2001, we, the people of the world, have suffered wars, bombs, attacks etc because four people on this planet; President Bush, Prime Minister (PM) Tony Blair, President Saddam Hussain and Osama Bin Laden did not like each other. Now, with the death of Osama and Saddam and the departure of President Bush and PM Tony Blair from world politics, I hope the next 10 years will be spent in peace and happiness.
