Pakistan's Taliban, one of the world's most feared militant groups, are preparing for a leadership change that could mean less violence against the state but more attacks against U.S.-led forces in Afghanistan, Reuters reported.The current leader, Hakimullah Mehsud, has fallen out of favor within the organization due to his penchant for violence, Reuters said, and is likely to be replaced by his more moderate deputy leader Wali-ur-Rehman.Under Rehman, the Pakistan Taliban could step up attacks across the border against U.S. troops in Afghanistan, potentially complicating U.S. plans to withdraw fighting forces from Afghanistan in 2014. The U.S. is already battling Taliban fighters in Afghanistan as well as the terrorist Haqqani network in Pakistan.Source: Reuters
