It is the second time that we have blackened our face as proverbial dealers of coal. At first time late General Zia-ul-Haq had said during the culmination of Afghan War with USSR that we had blackened our face as dealers of coal. Now while the USA is blaming Pakistan about finding Osama in Abbotabad and killing him by unilateral covert action, it is Pakistan that has suffered tremendous loss in life and limb of its soldiers as also of citizens. As such it is preposterous that USA is doubting the role of Pakistan and India encouraged by this illegal action is bragging that it could enact a similar unilateral action against Pakistan. Our country has got itself embroiled in endless war with our tribal people who were considered to be our strength by Quaid-i-Azam who withdrew army from the areas. What is required is a tough stand by our nation so that we are not struck by our own shoes on our heads by thankless America that ignores our colossal sacrifices as if we are pawns in their global war against terrorism.
