WASHINGTON –SeniorPakistani leadership knew that Osama bin Laden was hiding at a compound in Abbottabad but US has not been able to get any proof of it so far, said Hillary Clinton, the Democratic presidential front-runner who was the secretary of state at the time of the military operation. Hillary, 68, was the top adviser to US President Barack Obama on the decision to kill AlQaeda founder on May 2, 2011.In an interview to the CNN broadcast, she said it was just too much of a coincidence… that unusual-looking house would be built in that community near the military academy, surrounded by retired military professionals even though “we could not prove it.” “There was never any evidence that we could uncover that led directly to the top of the military and intelligence service in Pakistan. I believe Pakistanis knew,” she said.Obama’s aides stressed that the next commander-in-chief will for sure need a blend of the fine-grained intelligence work and surgical force that defined the lethal 2011 strike against AlQaeda’s mastermind, it said.
