ISLAMABAD - Army Chief General Ashfaq Parvez Kayani is working to repair his armys wounded pride in the bitter aftermath of the raid that killed Osama bin Laden, a humiliation that has strained US-Pakistani relations and raised questions about the top generals own standing, reports Washington Post. Retired and serving officers interviewed spoke of seething anger within army ranks over the secret strike the Americans carried out on May 2, undetected by Pakistans military. The US helicopter-borne operation set off a nationalist backlash: The usually untouchable army was sharply criticized in the press and on television talk shows, people demonstrated here in the capital demanding accountability, and open calls were made for the resignation of Gen Kayani. The army is Pakistans strongest institution, and Kayani the nations most powerful leader, but he has to be very careful, said retired Lt. Gen. Talat Masood. Like others interviewed, he doubted Kayanis underlings would try to unseat him in an intra-army coup, but he noted occasions in the past when disgruntled officers were found to be plotting against their chief. Last months raid on the al-Qaida leaders Abbottabad compound resurrected public comparisons to that Bangladesh debacle. In one sign of dented military prestige, Supreme Court ordered the withdrawal of a two-star general after his men were caught on video killing an unarmed youth. The court took the unusual actionin light of the hostile environment in the society toward the military, said defense analyst Hasan Askar Rizvi. The public disquiet weighs heavily on the officer corps and down through lower ranks, Masood said. It could all result in loose talk, he said, but he thought it wouldnt go beyond that. He noted that within days of the bin Laden raid, Kayani met with key corps commanders in an effort to assure his ranking officers they had not been humiliated. Theres quite a lot of anger within the military, retired Gen. Jehangir Karamat, a former chief of staff himself, said in a telephone interview from the eastern city of Lahore. Maybe there is talk, he said. Maybe anti-US feeling has gone up in the army. But actually there is in the country a whole lot of anger over the way it happened and the humiliation suffered, and it is inevitably reflected in the army. But, he added, all this talk of him fighting for his job, his survival, I dont see any signs of that. Kayani is consistently described as a professional soldier by his own men and knowledgeable foreigners. But the general, who as a younger officer did some training in the US, may face criticism because of the Pakistan Armys close past cooperation with the US military and dependence on US aid. Observers here said the fracture with Washington could set back military-to-military relations between the two countries by years, as the Americans seek to step up the joint fight against Qaeda and other militant groups in the Afghan border area. There is a very strong resentment, a very strong sense of betrayal of being discredited in the eyes of our own public. What our enemies have not been able to do they (the US) have done to us, said a senior military official, who asked that his name not be used to speak candidly.
