Terrorists always had to elude and adapt to state’s counterterrorism actions. Moving within both a clandestine and hostile world, Terrorist Organizations implemented Techniques, Tactics and Procedures (TTP) on terrorist attack cycle and target selection. Often, terrorist organizations operate like state actors. Not only operating with the same security measures and statecraft but also cooperating and making alliances.
