PRESIDENT Asif Ali Zardari had dismissed a suggestion by then US Ambassador Anne Patterson that Taliban leader Baitullah Mehsud was responsible for Benazir Bhuttos death, saying he was 'just a pawn in the process, according to a WikiLeaks expose. Zardari said he was not very much interested in who the sniper was or exactly how Benazir was killed. This was not as important as finding out who financed the killing, and who were the 'hands behind it. Benazir Bhutto returned to Pakistan after getting a clearance from the US, Zardari told Patterson after Bhuttos assassination, the US embassy cables revealed. Zardari met Patterson Jan 25, 2008, and said the US was their safety blanket and recalled how Benazir had returned despite threats against her, because of support and clearance from the US. Zardari said he had a one-page handwritten will from Benazir in which she bequeathed the Pakistan Peoples Party (PPP) to him. This document, he said, would be published in an upcoming book authored by Benazir. Meanwhile, Pakistan Army had offered to mediate between the US with Taliban leader Mullah Omar, said Afghan intelligence chief Amarullah Saleh, a diplomatic cable unveiled by whistle-blower website WikiLeaks has revealed. According to the leaked cable, in mid-2009, Saleh told a briefing of foreign diplomats that Pakistan army had offered the role of arbitration in USs talks with Omar. NDS Chief Saleh stated that the Pakistan Army has said they are ready to mediate between Mullah Omar and the US. Amb. Eikenberry said that the US has reaffirmed to Pakistan our policy that reconciliation is led through the government of Afghanistan, the cable said. In another 2009 cable, Hamid Karzai reported Pakistani intelligence officials had alleged to Afghan officials that the US intended to divide Pakistan and weaken Afghanistan in order to pursue its fight against terrorist groups.
