Pakistan's Army and ISI are covertly sponsoring four militant groups, including LeT, and will not abandon them for any amount of US money. As per the diplomatic cables released by WikiLeaks,the American envoy to Islamabad Anne Patterson wrote this in a secret review of Afghanistan-Pakistan strategy in September 2009. Patterson also underpinned the need for the US to reassess India's role in Afghanistan and the US policies towards India, including the growing military relationship through sizeable conventional arms sales. She said all of this feeds Pakistani establishment paranoia and pushes them closer to both Afghan and Kashmir-focused terrorist groups while reinforcing doubts about US intentions. The latest cache of WikiLeaks documents also lay bare the deep concern of the US over the safety of Pakistan's nuclear weapons and the fact that Islamabad is producing them at a faster rate than any other country in the world. The US diplomatic cables also revealed that hundreds of millions of dollars in American military aid to Pakistan earmarked for fighting Islamist militants was not used for the desired purpose, but diverted to the government's coffers.
