In his article for Washington Post, former Pakistani ambassador to US, Hussain Haqqani said that the ties he forged with the then US President Barack Obama helped the US track down and kill former al-Qaeda chief Osama bin Laden.

"The relationships I forged with members of Obama’s campaign team also led to closer cooperation between Pakistan and the United States in fighting terrorism over the 31/2 years I served as ambassador. These connections eventually enabled the United States to discover and eliminate bin Laden without depending on Pakistan’s intelligence service or military, which were suspected of sympathy toward Islamist militants," he wrote.

"Friends I made from the Obama campaign were able to ask, three years later, as National Security Council officials, for help in stationing U.S. Special Operations and intelligence personnel on the ground in Pakistan. I brought the request directly to Pakistan’s civilian leaders, who approved. Although the United States kept us officially out of the loop about the operation, these locally stationed Americans proved invaluable when Obama decided to send in Navy SEAL Team 6 without notifying Pakistan.

Unfortunately, the United States did not attain victory in Afghanistan, and the Pakistani government’s behavior toward militant Islamists did not change on a permanent basis. But for the period I was in office, the two nations worked jointly toward their common goals — the essence of diplomacy," he wrote. 

While mentioning his services as ambassador, Haqqani further added: "I became Pakistan’s ambassador in May 2008, soon after the country’s return to civilian rule after nine years of military dictatorship under Gen. Pervez Musharraf. The George W. Bush administration had forged an alliance with Musharraf in the aftermath of the 9/11 terrorist attacks, hoping that economic incentives and offers of military hardware would turn Pakistan away from its long-standing policy of supporting Islamist militants, including the Afghan Taliban, as instruments of regional influence."

"By 2007, Bush had realized that Musharraf either “would not or could not” fulfill his promises in fighting terrorism, as he wrote later, and the president welcomed Pakistan’s return to democracy. The civilian leaders who appointed me as ambassador — President Asif Ali Zardari and Prime Minister Yousuf Raza Gilani — looked forward to U.S. backing in reversing Musharraf’s policies at home and abroad. They said they wanted to end Pakistan’s support for the Taliban, improve relations with India and Afghanistan, and limit the role of Pakistan’s military intelligence service in defining the country’s foreign policy. In return, they sought generous U.S. aid to improve the ailing Pakistani economy," he mentioned. 

"I had an advantage most ambassadors did not: I’d lived most of the Musharraf years in exile in Washington and had established close ties with members of Congress and others influential in policymaking. But I began my job in the middle of the 2008 election campaign, and I knew that the Bush administration’s policies might not continue under a new president. Within weeks of presenting my credentials to Bush that June, I was communicating with campaign officials in both parties, and soon had meetings with aides to both Sen. John McCain and Sen. Barack Obama," he added. 

"The State Department facilitated the participation of Washington-based ambassadors in the Democratic and Republican national conventions that year. In Denver and in Minneapolis-St. Paul, we were briefed by officials from both campaigns. More active and better-connected ambassadors, including myself, were able to meet personally with people we expected to have major roles in the conduct of foreign policy after the election. There was nothing unusual, let alone treasonable, in this," he maintained. 

"As a presidential candidate, Obama argued that U.S. success in Afghanistan was more important than the war in Iraq, which he had opposed. In a major speech that summer, he pledged to make “the fight against al-Qaeda and the Taliban the top priority.” He also had a particular message for my country: He said terrorists and insurgents in Pakistan’s tribal areas were waging war against the Afghan government. “We must make it clear that if Pakistan cannot or will not act, we will take out high-level terrorist targets like bin Laden if we have them in our sights," the former ambassador wrote. 

"From Obama’s public positions and from my meetings with his aides, it was clear that a democratic, civilian government in Pakistan could join with him to help attain his objectives in Afghanistan in exchange for support of consolidation of democracy with greater U.S. economic assistance. I sent this message to my bosses in Islamabad and told Obama’s campaign team that we would be willing to play ball. Once Obama took office, this is exactly what happened: Civilian aid to Pakistan was enhanced to record levels in an effort to secure greater cooperation in defeating the Taliban," he said.
