Militant attacks on Afghan and foreign forces are orchestrated across the border in Pakistan, a top US military official said on Friday, a day after President Barack Obama announced the year-end review of the war strategy. Pakistani forces could eliminate the Taliban hideouts on its soil to stop the cross-border incursions into Afghanistan, US Navy Adm. Mike Mullen, chairman of the Joint Chiefs of Staff, told a news conference in Kabul. "I believe it's very much possible the Pakistani military will achieve the goal," he said, explaining the US had repeatedly taken up the issue with the nuclear-capable South Asian country. Islamabad was doing its bit to deal with the problem, he added. A day earlier, when Obama claimed the US and its allies had made considerable -- but fragile -- progress in Afghanistan, Mullen visited Camp Hanson in southern Helmand province. He met US soldiers, Marines, airmen and sailors at Camp Hansen near Marja and troops in Kandahar. With regard to the annual review, he said US officials had concluded they had to keep their focus on consolidating the gains achieved in different sectors in Afghanistan in recent years. The global fraternity needed to learn from past mistakes and see to it they were not repeated, he continued. Better governance is one way of protecting the progress, according to Mullen, who warned: "The gains will be lost if good governance and civic responsibilities are not assumed by the Afghan government with the same speed and courage as that shown by troops on the ground." The US would be able to begin a responsible reduction of forces in July 2011 when lead security responsibility would be handed over to the Afghans, in accordance with the timelines established by Obama, Karzai and NATO members, he continued. The admiral hoped the transition process would enable Americans to step up efforts on the civilian side, because progress on the battlefield had to be matched by gains on the governance front. Speaking on the occasion, US Ambassador Karl Eikenberry also voiced concern at the continued existence of militant safe havens in Pakistan. The terrorist bases on Pakistan's soil posed a serious threat to peace and reconciliation in Afghanistan, he remarked. Washington was fully appreciative and supportive of President Karzai's peace effort, said the diplomat, who linked regional security to the situation in the conflict-devastated country. On Thursday, Obama acknowledged the conflict in Afghanistan continued to be a difficult endeavor, though the US had made significant progress. Washington remained on track to achieve its goals of disrupting, dismantling and defeating Al-Qaeda and undermining its ability to threaten Americans and their allies in the future, he said.
