Afghanistan is the graveyard of superpowers. Russia was buried here long ago. Now it's the turn of America. After eight years of futile war, the Obama administration is sending 30000 more troops. With these troops, America can secure a little more area may be but not the whole Afghanistan. That would cost hell of a lot more in lives and dollars and he fiendishly difficult. One wonders what America wants to achieve by targeting these poorest of the poor people in the most arid of the arid wasteland? -DR ABID RAUF ORAKZAI, Islamabad, December 2.
