The group that is most likely to use terrorism to achieve its goal is one that lacks military power to compete with strong nations.

Terrorism is defined as the use of violence as a means to cause terror or fear among masses of individuals in an attempt to achieve a religious or political purpose. Terrorism is usually perpetrated by small groups in order to de-stabilize a country by attacking directly its population so that they push its government to give in to the terrorists demands.
