WASHINGTON (AFP) - The nominee to be the next US ambassador to Pakistan on Thursday pledged ceaseless engagement to combat the countrys anti-Americanism, saying Washington needed to do a better job explaining its motives. Cameron Munter, a veteran diplomat in hot-spots such as Iraq and Serbia, said the United States should pursue a long-term commitment to help Pakistan fight extremism and recover from devastating floods. But in his confirmation hearing before the Senate, Munter said that US officials needed to be better listeners and build a lasting relationship with Pakistani counterparts based on honesty and mutual respect. Lets be honest about this. We need to overcome historical scepticism among Pakistanis about American motives in South Asia, and this will require ceaseless engagement, energy and outreach, Munter said. We will not always agree with Pakistan on every priority, but we will work through our differences as partners, with our eyes on a vision we share of the strong, independent Pakistan at peace with its neighbours and free of terrorism, he said. Senator Jim Risch, who is from the minority Republican Party, accused Pakistan of ingratitude, noting that the United States has committed the aid package despite a worsening national debt. Were encumbering our kids and our grandkids future, the Idaho senator said. We dont have any money anymore. Do they have even a modicum of appreciation for what Americans are doing for them? Risch said at the hearing. Munter replied: I dont think its a question that they dont know what were doing. The question is the scepticism of why were doing it. Munters nomination needs the approval of the full Senate, which is likely.
