ISLAMABAD - As Richard Holbrooke, Special US Representative for Afghanistan and Pakistan, arrives here today (Saturday) on a three-day visit to discuss the anti-terror strategy of US President Obama with Pakistani leadership, the diplomatic circles believe that he will ask for early commencement of military operation in South Waziristan. The United States wants Pakistan to eliminate the al Qaeda hideouts in Waziristan and curb the Taliban militancy and for that it believes the killing of Baitullah Mehsud, Pakistani Taliban chief, has provided a great opportunity, as his followers are in disarray and the problem of militancy could be tackled successfully if ground offensive is launched. Pakistani authorities, on the other hand, are not against launching a military operation in South Waziristan but before that they want to stabilise Swat, Dir and Buner where the Army flushed out Swati Taliban after months long offensive but still some of the areas are to be cleansed of the militants. The US envoy Holbrooke is expected to urge Pakistani leaders to go for an early ground offensive in Waziristan during his talks with President, Prime Minister and other officials in Islamabad, said a diplomatic source desiring not to be named. He said the Obama administration was also on board when it came to dialogue with the Taliban who were willing to shun militancy and distance themselves from al Qaeda. However, the US authorities want Pakistan to eliminate the elements who are not ready to opt for the path of dialogue and dissociate themselves from the al Qaeda, the source added. An official here when contacted said that he was unaware of any fresh demand by Washington for the initiation of military offensive in South Waziristan. Nonetheless, he admitted that the US authorities had been positive in their response to the desire expressed by Islamabad for talks with the moderate elements in the ranks of Taliban in the tribal areas. Holbrooke will discuss what the US authorities think about the Pakistani idea of talking to moderate Taliban and how it could be worked upon for lasting peace in the region, the official said.
