'Pakistan not taking adequate measures against Haqqani network'

General Martin Dempsey, Chairman of the US Joint Chiefs of Staff said, Pakistan was facing a huge internal challenge that could have caused it to fail. But he said, No one believes that a failed Pakistani state would be a good thing for the world, let alone the region as it sits in an extraordinarily important geostrategic location in a very challenging part of the world.The American General admitted that Pakistan is our most complex relationship. But in the same strain said Washington is committed to improve these strained ties. Speaking an event at the National Press Club here, Dempsey said though the relations were complex, but its an important relationship. The comments from the US top officials come at a time when the US is negotiating with Pakistan on reopening of ground lines of communication (GLOCs).The General said that the US remained committed to promoting peace in the region in the wake of roughly 44,000 civilian and 14,000 military deaths there since 9/11. Pakistan is our most complex relationship. I mean, theres softer way to say that. But its an important relationship. So, you know, I work at it. I work at it a great deal.The Pentagon official said he had met yesterday with the Pakistans Ambassador Sherry Rehman to talk about some of the issues that we confront.Theres no question that our ability to achieve the outcomes we have established for ourselves in Afghanistan will be impacted by that border with Pakistan. However I want to remind ourselves, and I remind others, that we have an important relationship with Pakistan because of Pakistan. So this isnt all about, we need Pakistan because of Afghanistan. I think we need a positive relationship with Pakistan because of Pakistan, Dempsey said.Pakistan, he said, havent been sitting outside much. They also havent been doing enough against the Haqqanis, and I was very clear about that. So this relationship is worth the effort. But were at in a pretty low point right now, Dempsey said.
