You seem old enough to have realized by now that the agenda at play belongs to the United States, and that terrorism is a tool of the state. Sure, sometimes it's genuine (they call this "blowback"), sometimes it's an FBI sting operation or a false flag drill, but in every case it's part of a plan to move the world towards a certain outcome where there is more control and less privacy and where recourses, human and otherwise, are continuously exhausted.

Taking a look at Islamic terror: the "agenda" is to rid themselves of foreign meddling in their land and way of life. Suicide bombing is not a weapon. Like in WWII, it's the last resort of a desperate people.

Look at it this way. If you life in the USA, or in the West in general, you basically live on the Deathstar. Life is great in the empire, but not so great in the outer rim where our stormtroopers police the galaxy.
