In 1953, a radical splinter organization from the Muslim Brotherhood,Hizb ut-Tahrir (HuT), was founded by the Al-Azhar University (Cairo,Egypt) educated jurist Sheikh Taqiuddin an-Nabhani who criticized theMuslim Brotherhood for collaborating with Egyptian secularists, such as Gamal Abdel Nasser. A sizable portion of the more radical members of the Muslim Brotherhood broke away, to join Nabhani's budding movement. Today, HuT is known to operate in more than forty countries, calling for the restoration of the Islamic Caliphate, with a history of violence and links to violent terrorist organizations. Given increasing tensions in the region over the presence of coalition troops, Predator drone airstrikes, a destabilized Pakistan, and lawless regions in Afghanistan, HuT is well positioned to amplify the strategic threat to coalition forces serving in the Pakistan and Afghanistan theaters.
