This should come as no surprise. It is in Pakistan’s best interest to keep Afghanistan as weak and unstable as possible. The US is trying to pay off the debt established by the Durand Line in 1893.
KABUL – Pakistani military intelligence not only funds and trains Taliban fighters in Afghanistan but is officially represented on the movement’s leadership council, giving it significant influence over operations, a report released on Sunday said.
The report, published by the London School of Economics, a leading British institution, on Sunday, said research strongly suggested support for the Taliban was the "official policy" of Pakistan’s Inter-Services Intelligence agency (ISI).
Although links between the ISI and Islamist militants have been widely suspected for a long time, the report’s findings, which it said were corroborated by two senior Western security officials, could raise more concerns in the West over Pakistan’s commitment to help end the war in Afghanistan.
