ISLAMABAD - Richard Holbrooke, the Special US Envoy for Pakistan and Afghanistan may demand a full-fledged military operation in South Waziristan in his talks with Pakistani leaders during his three-day visit to Islamabad that began on Tuesday. The special American envoy will urge the Pakistani leaders to go for a full-fledged operation against Taliban and al-Qaeda militants in Waziristan along with the ongoing small-scale offensives in Swat, Buner and Dir, said a diplomatic source here on Tuesday desiring not to be named. However, he said that despite the announcement by the Pakistani government to go after Baitullah Mehsud in South Waziristan and launch a military operation, there were no chances that troops were to be moved there in large number for an offensive anytime soon. The source said that Pakistan was in agreement with the United States on the need of military operation against Baitullah Mehsud but the difference of opinion was on the timing of that offensive. He said that Pakistan first wanted to consolidate its position in Swat, Dir and Buner, rehabilitate the people in their hometowns and ensure their safety before opening another war front in Waziristan. Once peace and order is restored in Swat, Dir and Buner then the government has no problem with ground operation in Waziristan and one should not forget that Pakistan Air Force is already pounding the militants hideouts there for the last couple of weeks to soft the target, the source said. An official here when contacted said that there was a desire in US capital for operations in Pakistani tribal areas but we believed that there was also an understanding of ground realities in Pakistan. The Americans know that opening of too many war fronts could have repercussions for Pakistans stability and I also believe that they also realise how important it is, so fully secure the Swat, Buner and Dir after a large-scale military operation there, the official said. When asked about other important items on the agenda of Richard Holbrooke, the official said that the US envoy would meet the President, Prime Minister and Chief of Army Staff and discussed with them other issues like American efforts for the normalisation of Indo-Pak relations. He said that the US envoy, whose visit to Pakistan coincides with that of Secretary of State, Hillary Clinton to India, was also likely to visit New Delhi after his trip to Islamabad and Kabul. Moreover, he said the American envoy would also visit the war affected areas in Swat and Buner during his current visit. Holbrooke was also likely to visit Lahore and meet the PML-N leader, Mian Nawaz Sharif, he added.
