US operations in Pakistan are under increased scrutiny today following Wednesday’s killing of three US soldiers in a roadside attack. The soldiers were traveling as part of a Pakistani military convoy and were reportedly wearing disguises. Another two US soldiers were wounded in the bombing. As recently as July, the Obama administration’s special envoy, Richard Holbrooke, denied a US military presence in Pakistan, saying, “People think that the US has troops in Pakistan. Well, we don’t.” But after Wednesday’s bombing, Holbrooke said, “There’s nothing secret about their presence.”
