WASHINGTON: - After signaling its reservations through news media citing unnamed U.S. officials, the Bush administration on Wednesday officially voiced its concerns over the peace deal Pakistan is negotiating with tribal militants. "We have expressed our concerns about this agreement," White House Spokesperson Dana Perino said in response to a question whether the accord the new Pakistani government is working on would succeed. "Obviously this is something that was tried before. It did not work before." And the White House spokesperson appeared to attach some conditions in case the deal is signed. "It's important that any agreement be effectively enforced and that it not interrupt any operations where we are going after terrorists in that area." Ms. Perino also said the United States was continuing to work with the new Pakistan government. "We think that we can work effectively with them and we have very clear and frank discussions to make sure they understand where we're coming from. At the State Department, spokesman Sean McCormack was  more diplomatic. "We understand that it is an attempt on the part of the Pakistani Government to try to peel away those people who are reconcilable to a political process, who want to integrate themselves into the fabric of Pakistani political life and actually want to have the FATA become a fully functioning part of Pakistan." He acknowledged the toughness of the problem in areas along the country's Afghan border in view of the fact that federally administered tribal areas have historically remained ungoverned. Washington, he said, supports the Pakistani government' positive goal of fully integrating the tribal areas and its people into the national political life but said those who irreconcilable to any political process have to be dealt through other means. "So, this is an attempt on the part of the Pakistani Government to try to achieve a positive goal.  And certainly, we support that.  Of course, any sort of political dialogue and outreach needs to be integrated with other kinds of efforts, security measures as well as economic and development measures," he stated of negotiations with local tribesmen Islamabad has started to isolate terrorists. As for what the new initiative might produce, McCormack remarked it remains to be seen. "We don't yet know.  There have been attempts in the past that have not succeeded.  That's a tough problem.  So we'll see what the current effort yields.  It's too early to tell." Pakistan has said it would not negotiate with terrorists but talk to tribesmen to secure their support in isolating terrorists and vowed to follow a multifaceted strategy to curb terrorism. Prime Minister Yousaf Raza Gilani Wednesday said comparisons between the fresh initiative and the previous one is erroneous as the government now is talking from a position of strength.
