There is no weight in the latest statement of (the Nobel Laureate) Barack Obama that 'justifies' killing of the poorest of the poor and most backward of the backward nation, Afghans, on the pretext of "defending the civilized world". The civilized world was never threatened by Afghanistan, even if some individuals ensconced there might have. The world peace has always been threatened by the most powerful nation of all, United States of America. Mr. Obama is right in saying that the blood of American citizens and the strength of their arms have protected the civilized world but it is the blood of world's weakest that America has sucked to fatten the American economy and military. -DR ABID RAUF ORAKZAI, Islamabad, December 11.
