I’m sorry, but I am not aware of any specific classification of terrorism into 8 phases.

What are the Different Types of Terrorism as Per Law

One popular typology identifies three broad classes of terrorism: revolutionary, subrevolutionary, and establishment.

What are the Four 4 Waves Theory of Terrorism

The four waves are, successively, the Anarchist wave (1878–1919), the Anti-Colonial wave (1920s–early 1960s), the New Left wave (mid-1960s–1990s), and the Religious wave (1979).

Which of the Following Steps has the World Community Taken to Combat Terrorism

There have been a number of steps that the international community has taken to combat terrorism, including:
Adoption of International Conventions and Agreements: Many countries have signed and ratified international agreements that provide a framework for cooperation and assistance in the fight against terrorism. These agreements can help to ensure that countries are working together to combat terrorism and that individuals who are suspected of terrorist activities can be brought to justice, regardless of where the crimes were committed.

Creation of International Organizations: Several international organizations have been established to help coordinate efforts to combat terrorism at the global level. Examples include the United Nations Counter-Terrorism Committee and the Global Counter terrorism Forum.

Use of Sanctions: Some countries have imposed economic and other types of sanctions on individuals, organizations, and countries that are believed to be supporting or financing terrorism.

Military Intervention: In some cases, countries have intervened militarily to help combat terrorist groups, either alone or as part of a coalition of nations.

Countering Violent Extremism (CVE) Programs: Many countries have implemented programs aimed at preventing radicalization and recruitment into terrorist groups. These programs can involve a range of activities, such as providing alternative narratives to counter extremist ideology, promoting intercultural dialogue and understanding, and supporting efforts to rehabilitate and reintegrate individuals who have been radicalized but wish to leave the extremist movement.
