From the devastation of 9/11 to the horror of the 　　London bombings, acts of terrorism have left their mark 　　across the world. 　　The series looks at the groups behind the attacks: their 　　potted histories, their leaders and how some groups 　　even mutated into legitimate political parties. 　　How did terror groups active in Israel after World War 　　II eventually transform into modern day Mossad? What 　　factors finally brought an end to the urban warfare, 　　typified by indiscriminate car-bombings and tit-for-tat 　　sectarian shootings, in Northern Ireland? Why was 　　Osama Bin Laden able to cause so much damage to 　　the Twin Towers? Why is it that one terrorist group fails, 　　while another prospers and develops? 　　With the use of rare archive footage, expert testimony 　　and 3D graphics, this incisive series seeks to answer 　　those questions, and many more. 　　Episodes include: 　　Israeli vs Arab 　　Al Qaeda and Bin Laden 　　The IRA 　　Fatah and Hamas 　　The PLO 　　ETA 　　The Red Brigades 　　Baader Meinhof 　　The EOKA 　　Nasser and Egyptian Terrorism 　　Colonel Gaddafi and Libya 　　Algeria and the OAS 　　The SLA and Patty Hearst 　　The Weathermen (USA) 　　US Survivalists (Timothy McVeigh) 　　Ku Klux Klan 　　Japanese Sarin Cult 　　The Mahdi Army 　　Che Guevara 　　Fidel Castro 　　ANC and Nelson Mandela 　　The Mujahadeen 　　The Radfan Rebels 　　The Tamil Tigers 　　The Moluccan Separatists 　　Somali Warlords
