From The Financial Times:
“The US now has information that Pakistan, particularly the ISI, gave access to the Chinese military to the downed helicopter in Abbottabad,” said one person in intelligence circles, referring to the Pakistani spy agency. The Chinese engineers were allowed to survey the wreckage and take photographs of it, as well as take samples of the special “stealth” skin that allowed the American team to enter Pakistan undetected by radar, he said.
Despite brave words on both sides, the US-Pakistan alliance is dying a slow and painful death. Some Pakistanis in the military and the ISI think the US has made a strategic choice for India and can no longer help Pakistan with its key objectives. The Obama administration cannot kick this can down the road forever; the US must develop a policy for south and central Asia which assumes Pakistani hostility to most of our key objectives.
