NEW YORK - Despite repeated denials by Pakistan about the presence of Mullah Muhammad Omar and other Taliban leaders on its soil, a civilian adviser to US military has called for targeting them in Balochistan. 'The cost of failing to act in Balochistan will be enormous, Seth Jones, a senior political scientist at the RAND Corporation, a Washington-based think tank, wrote in the New York Times on Friday. 'The United States and Pakistan must target Taliban leaders in Balochistan, he said, while making the case for actions against the militant leaders supposedly residing in the largest Pakistani province. 'There are several ways to do it, and none requires military forces, Jones wrote in an op-ed piece from Kabul. Jones said: 'The first is to conduct raids to capture Taliban leaders in Balochistan. Most Taliban are in or near Baloch cities like Quetta. These should be police and intelligence operations, much like American-Pakistani efforts to capture Khalid Shaikh Mohammad and other Qaeda operatives after 9/11. The second is to hit Taliban leaders with drone strikes, as the US and Pakistan have done so effectively in the Tribal Areas. Regretting that no substantive action had been taken against the Taliban leadership in Balochistan province, the adviser to US military said, 'This is the same mistake the Soviets made in the 1980s, when they failed to act against the seven major Mujahideen groups headquartered in Pakistan. This sanctuary is critical because the Afghan war is organised and run out of Balochistan. He said virtually all significant meetings of the Taliban take place in that province, and many of the groups senior leaders and military commanders are based there. 'Like a typical business, the Taliban in Pakistan have an organisational structure divided into functional committees. It has a media committee; a military committee; a finance committee responsible for acquiring and managing funds; and so forth. The Talibans inner shura, or governing council, exerts authority over lower-level Taliban fighters. It is composed of the supreme Taliban leader, Mullah Muhammad Omar, his principal deputy, Mullah Abdul Ghani Baradar, his military commander, Abdullah Zakir, and roughly a dozen other key leaders. Many Taliban leaders have moved their families to Balochistan, and their children attend Pakistani schools, he added. 'Mullah Baradar is particularly important because he runs many of the shuras involving senior Taliban commanders, virtually all of which are in Pakistan, he said. 'Yet Pakistan and the United States have failed to target them systematically. He further said that Pak Army and Frontier Corps forces have conducted operations in Pakistans Tribal Areas to the north, and the United States has conducted many drone strikes there. But relatively little has been done in Balochistan. Meanwhile, US lawmakers lashed out at Pakistan on Thursday as an unreliable ally that could spare the US its bruising fight with al-Qaeda if it wanted. 'They dont seem to want a strategic relationship, Democratic Senator Bob Menendez said of the government in Islamabad. 'They want the money. They want the equipment. But at the end of the day, they dont want a relationship that costs them too much. A crucial ally in fighting the al Qaeda terrorist network, Pakistan is also a major recipient of US aid, it was pointed out. President Barack Obama and Congress recently approved a $7.5 billion aid package for economic and social programmes in Pakistan in a bid to strengthen the civilian government there. 'It is not clear how an expanded military effort in Afghanistan addresses the problem of Taliban and al-Qaeda safe havens across the border in Pakistan, said Sen. Richard Lugar, the top Republican on the Senate Foreign Relations Committee. Congressman Ike Skelton, a leading conservative Democrat, said Obamas strategy was the best US shot but that Pakistan could end the war if it wanted. 'Conversely, if Pakistan were to return to old habits of supporting the Afghan Taliban, the war may be almost impossible to win, he said. Obama has sought to assure lawmakers - and the rest of the world - that he sees Pakistan inextricably linked to Afghanistan. In his speech on Tuesday, the President said both governments were 'endangered because of al Qaeda. 'The stakes are even higher within a nuclear-armed Pakistan, because we know that al Qaeda and other extremists seek nuclear weapons, and we have every reason to believe that they would use them, he said in his speech from West Point. Testifying for the second day on Obamas new war plan, the Presidents chief military and diplomatic advisers said Pakistan was a critical component of the strategy. 'We have a lot of work to do in trying to convince them that were not trying to take over their country, that were not trying to take control of their nuclear weapons, and that we are actually interested in a long-term partnership with them, said Defence Secretary Robert Gates. Several Democrats, including Menendez and Sen. Russ Feingold, have threatened to withhold their support for more money for the war, although lawmakers said it was unlikely that Congress would try to block the deployments. Instead, members from both parties say they want to find a way to pay for the troops increase that wont add to the deficit. In a news conference Thursday, the Leader of the House, Speaker Nancy Pelosi, said she did not support a proposal by Wisconsin Democratic Congressman David Obey that would have imposed a war tax on most Americans. Pelosi, a Democrat, said the first step should be an all-hands briefing to Congress by Obamas top advisers. 'We have to handle it with care, listen to what they present, and then members will make their decision, she added.
