Which of the following is NOT the organizational level of international terrorism?

Organizational levels of terrorism are generally classified into:

Individual Terrorism (Lone-wolf actors)

Group Terrorism (Non-state groups like al-Qaeda, ISIS)

State Terrorism (When a state uses terror tactics on its own or others' populations)

Modern terrorism refers more to the contemporary methods, tools, and global nature of terrorism—not a level of organization. Hence, it's not considered an "organizational level."
