ISLAMABAD - The US demand to 'do more can be heard soon once it is confirmed publicly that the banned Tehrik-e-Taliban chief Baitullah Mehsud, considered to be Pakistans enemy no 1, is no more alive. The US achieved two goals from the killing of the most-wanted Taliban commander: moralise the unwanted drone attacks and exert more pressure on Islamabad to respond in the same manner by targeting other three militant commanders, Washington believes are responsible for sending fresh suicide recruits to Afghanistan. Analysts and people privy to the development fear that Mehsuds killing will have far-reaching impact on Islamabad in terms of backlash from the militants. The official circles are still looking into the matter and trying to confirm with some credible substance the killing of Baitullah Mehsud, reportedly hit by a missile strike in Zangarha area of South Waziristan Agency on August 5 (Wednesday) by an unmanned spy plane. Not only the official circles but some Taliban sources are also indicating that TTP chief is dead in the said drone attack on the house of Malik Ikramuddin, the father-in-law of Baitullah, in which he, his wife and 7 other militants were reportedly killed. Rustom Shah Mohmand, a former diplomat and senior security analyst, told TheNation that the government should not be over jubilant on the killing of Baitullah in a drone attack. I see this attack can increase the drone missile strikes thus legitimising the killing of the most wanted man, but at the same time provoking the militants to step up their acts of terror in Pakistani, he feared. However, he also considered the killing of Taliban chief as a breakthrough for Pakistan as well as the US that they finally killed a top militant in war against terror. The killing of Taliban Commander may also affect the movement of Pakistani Taliban as they no more have among their ranks as towering a personality as that of Biatullah to lead TTP, he commented. He said he could also see clear cracks appearing in the ranks of Taliban and if they did not shun differences, there could be another setback to Pakistani Taliban in the days ahead. However, he said now the chances for a full-scale military operation have also become very little and the security forces would continue with some targeted action to curb militancy. After the killing of Baitullah, the government has also stepped up security to avoid any fallout of the current scenario in shape of recurrence of suicide attacks and bomb blasts stalled for the past three weeks. The government may face fresh demand from Washington to extend action against the militants in other tribal regions as well and also launch a major offensive in the South Waziristan to clear the area of the militants.
