WASHINGTON - The United States expects Pakistan to combat the militants intent on engaging in extremist action and violence while continuing efforts to win over the support of reconcilable segments as part of Islamabad's multi-pronged anti-terror strategy to deal with the situation on the border with Afghanistan. "But there is no silver bullet. There is no single solution here," State Department Spokesman Tom Casey said in response to a question at the regular noon briefing.  "Certainly, we support efforts to bring those who are outside the current political process into the political process. At the same time, we would certainly hope that any discussions or agreements reached would, clearly, ensure that there would be a halt to violence and that those that might be engaged in extremist activities or violence ended such activities," he added. Referring to the Pakistan government's declaration Wednesday to employ a multi-pronged approach to weeding out terrorism, the spokesman said they would not find any extremist activity on their soil acceptable. "There have been declarations made by senior officials in Pakistan, both political party representatives, those from the military, and some of the traditional leaders in the FATA that reiterate their opposition to extremism and their desire and willingness to combat it," the spokesman said. "Obviously, we would not want to see anything done that would allow safe haven for extremists or would allow extremists to be able to carry out attacks, either in Pakistan or elsewhere in the region, specifically cross-border with Afghanistan. But again, I think there is certainly clear statements from the Pakistani Government that is not something that they would find acceptable either." He said it's better to have people that are illegally taking up arms and engaged in violence and extremism stop it and acknowledged stopping that involves a variety of things including economic and security measures. "It involves kinetic actions. It involves military actions. It involves dialogue with those that are willing to lay down their arms and join peacefully in the political process. It involves economic development and political development so that there are strong institutions that are able to provide services for the people, able to provide justice for the people, and able to deal with those who commit acts outside the system." "But there is no silver bullet.  There is no single solution here. And I think if you look at instances and places where there has been an effective response to extremism, it has involved all of those various tools in one form or another. But each set of circumstances is unique and different. Certainly, we would expect that the Government of Pakistan would do everything that it could to combat those who continue to be intent on engaging in extremist action and engaging in violence. "But certainly, there is not any predisposition to reject discussions that would lead to individuals who might otherwise be taking up arms or willing to provide material support, or simply willing to stand by and take no action while extremist groups are operating."
