It's such a funny use of words, it's not a war of terrorism, or terrorist, but terror.

Terror is defined as

1. intense, sharp, overmastering fear: to be frantic with terror.
2. an instance or cause of intense fear or anxiety; quality of causing terror: to be a terror to evildoers.
3. any period of frightful violence or bloodshed likened to the Reign of Terror in France.
4. violence or threats of violence used for intimidation or coercion; terrorism.
5. Informal. a person or thing that is especially annoying or unpleasant.

The U.S and U.K and others are causing just this by starting wars.

We can stretch the word Terror to Terra, which is Aton for Earth.
To quote Michael Tsarion,
"The WAR ON TERRA is merely the latest move in the great game played out by the Atonist Establishment, the Royals, and Vatican Jesuit-Masonic elites who expertly employ the Dialectic ("Ordo Ab Chao") to further their very personal aspirations which date back to an old world order that you are supposed to know nothing about."

The War on Terror is actually a war on Terra/Earth.
