The US troubleshooter on Afghanistan and Pakistan was due in Islamabad Monday to forge a new strategy and urge US allies to do more in the fight against Islamist militants. Richard Holbrooke, considered a hard-hitting diplomat and the architect of peace in Bosnia, will visit Pakistan as part of a regional tour that includes Afghanistan and India. US President Barack Obama has called Afghanistan the main front in the "war on terror" and plans to send a further 30,000 troops, doubling the US military contingent fighting a Taliban-led insurgency alongside 50,000 NATO troops. Holbrooke, who will be responsible for implementing an integrated US strategy towards Afghanistan and neighbouring Pakistan, will "report back" to Secretary of State Hillary Clinton and Obama, US officials have said. "He's not carrying any messages to any of these governments from either the secretary or the president. And he's not going there to lecture, he's going there to listen," State Department spokesman Robert Wood said last week. Holbrooke's mission comes amid turmoil in relations between India and Pakistan over the Mumbai attacks, which New Delhi has blamed on Pakistan-based militants. Ties between Islamabad and Washington are also strained, over US missile strikes within Pakistan and US criticism that Pakistan is not doing enough to eradicate Islamist "safe havens" on its territory. Pakistan, reeling from attacks that have killed more than 1,500 people in the past 20 months, says it will welcome any policy review. "It is Pakistan's endeavour to develop a fresh perspective on issues of peace, security, stability and the development of the region and in particular address the issues of militancy, terrorism and extremism effectively, by adopting a comprehensive and holistic strategy," the foreign ministry said in a statement ahead of Holbrooke's arrival. The United States is also seeking assurances from Pakistan that controversial nuclear scientist Abdul Qadeer Khan, who was freed from house arrest last week, will not be involved in atomic proliferation. Holbrooke will meet President Asif Ali Zardari, Prime Minister Yousuf Raza Gilani and Foreign Minister Shah Mahmood Qureshi during his three-day visit after his arrival Monday, the foreign ministry said. Addressing a security conference in Germany Sunday, Holbrooke called for a regional approach and urged allies to contribute more to the fight in Afghanistan. "It is like no other problem we have confronted, and in my view it's going to be much tougher than Iraq," he said. "What is required in my view is new ideas, better coordination within the US government, better coordination with our NATO allies and other concerned countries, and the time to get it right," he said. Afghanistan's neighbours are also part of the solution, he said, particularly Pakistan, which joined the "war on terror" after the September 11, 2001 attacks on the United States. "Pakistan's situation is dire," he said. "It needs international assistance, international sympathy and international support." Pakistan wants the US missile attacks to end, US aid (10 billion dollars under ex-ruler Pervez Musharraf) and renewed diplomacy on Kashmir, an issue at the heart of its troubles with India but which Washington says is not within Holbrooke's mandate. Senator Khurshid Ahmad, a member of Pakistan's upper house of parliament for the main Islamist party Jamaat-i-Islami and head of an independent think thank, said the government had to make clear demands of the US. Pakistan had incurred huge losses by participating in the "war on terror" for which "the US must compensate us," Ahmad said. "We should clearly tell the US envoy that without resolving the Kashmir issue, there cannot be peace and security in the region," he added. On Monday, the results of Pakistan's investigation into the Mumbai attacks that killed 165 people in November will be presented to cabinet ministers and army chiefs at a meeting chaired by Gilani.
