President Asif Ali Zardari stopped the Pakistan Army from conducting an operation in Waziristan, WikiLeaks revealed. In a diplomatic cable sent to Washington on October 6, 2009 the then ambassador to Pakistan, Anne W Patterson wrote about her meeting with Army Chief Kayani. According to the cable, Kayani informed her that President Zardari had stopped the operation in Waziristan till spring due to political reasons. During their meeting, the COAS informed the US ambassador that he had met Punjab Chief Minister Shahbaz Sharif and opposition leader in the National Assembly Chaudhry Nisar, but the purpose of this meeting was not political. ISI Chief Lt-General Shuja Pasha was also present during the meeting between the US ambassador and the Army Chief. According to the cable, both Kayani and Pasha opposed certain aspects of the Kerry-Lugar Bill stating that they were against the Pakistan Army and would negatively impact Pak-US relations. On the issue of back channel diplomacy with India, the COAS said that the US ambassador should speak with President Zardari. The cable also stated that both Kayani and Pasha wanted back channel diplomacy with India to be successful. Meanwhile, former Prime Minister Benazir Bhutto thought the PML-N chief Nawaz Sharif a weak and not much capable person, but she disliked Shahbaz Sharif more, who to her appeared more intelligent than Nawaz, but much more cruel. According to WikiLeaks, US embassy in a diplomatic analysis sent on August 31, 1998 referring to Benazir views said that Shahbaz Sharif in her views was though more intelligent than his brother, but much more cruel than Nawaz Sharif. And in this connection she quoted the instance of that bureaucrat, whom Shahbaz had ordered to keep standing in the stinking water.
