ISLAMABAD The Pakistan Army top brass has conveyed to the United States that the drone strikes in the tribal areas are counter-productive, as they are alienating the local population and spreading anti-Americanism in the region. The message was conveyed in separate Thursday meeting of United States Central Command (Centcom) Commander General James N Mattis with Chief of the Army Staff (COAS) General Ashfaq Parvez Kayani at the Army House in Rawalpindi and Chairman Joint Chiefs of Staff Committee (CJCSC) General Khalid Shameem Wynne at Joint Staff Headquarters, Chaklala. Both sides discussed regional security situation and other matters of professional interest, including the situation in Afghanistan and Pak-US bilateral military cooperation, said an ISPR statement. Agencies add: According to sources, both the high-ups made their assurance that military assistance between both the countries will be further bolstered. The COAS, however, expressed profound reservations on the White House report. Gen Kayani said Pakistans security forces have done tremendous job and tackled terrorists with iron hands. General Kayani and General Mattis discussed a number of issues, with Gen Kayani stressing that Pakistan has played a brilliant role in the war against terrorism while its sacrifices and services are hard to be undermined. General Mattis highly acclaimed the role of the Pakistan Army, adding that it has always played a significance role in countering militancy and extremism. He added that the US will keep on supporting the Pakistan Army thick and thin to cater to its defence needs. Sources said the security situation, especially that in Afghanistan, and Pakistan-US bilateral military cooperation also came under discussion. General Mattis said the role of the Pakistan Army is unquestionable. Meanwhile, a report said Director General Inter Services Intelligence (ISI) Lt-Gen Ahmed Shuja Pasha would visit Washington from April 11. Sources said the purpose of Pashas visit is to remove misunderstandings between the ISI and the CIA which appeared on the issue of Raymond Davis. Sources said that General Pasha would also raise the issue of drone attacks in the tribal areas. The DG ISI was invited by his US counterpart Leonne Panetta. The two dignitaries are in constant touch for the restoration of the confidence, sources added. Gen Mattis was the visit of the most senior American since the release of CIA contractor Davis. Lieutenant Colonel Michael Shavers at the US Embassy told AFP that Mattis intended to hear from them (Pakistani Generals) their concerns with regard to the relationship with the US military here. Hes going to be in listening mode... thats the main reason why hes here, he said before the meeting. Mattis aims to visit Pakistan every three months and last visited in November, Shavers added. Aside from military operations, more than 4,200 people have been killed across the country since 2007. But a US report this week criticised the Pakistani military for failing to forge a clear and sustained path to beat the insurgents.
