The May 2 Osama incident was bound to unfold fresh challenges for Pakistan every day, leaving it wide open how things finally settle down between Pakistan and the US. Islamabad maintains that the presence of bin Laden at Abbottabad took it unawares, while Washington has its reservations about this claim unless it could be established with some credible evidence. From within the country, Pakistan security forces have been accused of being caught napping, as the US Navy Seals carried out their mission on its soil, or of being complicit in the operation. Whatever the actual position, the ISI has come in for a lot of flak, cutting a sorry figure at its failure. CIA Director Panetta, forgetting his agencys disastrous lapse to unravel the plot to brig down the Twin Towers, has virtually sneeringly talked of ISIs incompetence to detect that Osama was living in that compound or its complicity in his stay. There have been calls for stopping aid to Islamabad or putting it under further scrutiny and, on the other hand, attempts to silence these voices by asserting that it is an important ally in the war on terror that has suffered more than any other country and should continue to receive all required help. Now, a week after the event, it appears that Mr Obamas promised visit to Pakistan has been put on hold, with the White House saying that he has no such visit scheduled this year. Mr Obama and some other influential American officials and Congressmen have started asking probing questions from Pakistan. Mr Obamas call for a probe into a possible support network, whether located in government circles or outside, for Osama in the country would be, even without his demand, on the agenda of any investigator. On the other hand, US National Security Adviser Tom Donilon, while maintaining that he had not seen any evidence as yet that Pakistans civil or military authorities were aware that bin Laden was living there, the countrys knowledge of his whereabouts needs to be investigated. Pakistans concerned agencies have set in motion the process of inquiring into the different aspects of the Abbottabad episode. But a weak and corrupt leadership, presiding over a crumbling economy and running a country with mounting public discontent threatening to blow up, is being subjected to a rising crescendo of pressure from the US. There is need for Islamabad to understand the rationale of this pressure and take steps to withstand it. In bin Ladens incident, the US has found an ideal scapegoat in Pakistan for its failure in Afghanistan. It will do all it can not to let it off the hook. Unless our leadership sheds its compliant behaviour towards the US and puts up a firm, nationalistic stand, Pakistan is in for real trouble. It should take a cue from Iran and North Korea which have, despite being heavily sanctioned, successfully rebuffed the superpowers demands.
