Although both Insurgency and Terrorism wage a violent struggle or war to overthrow the existing constitutional government yet there is difference between the two.
(a) Insurgency is confined within the national boundary and it is directed against one’s own government. On the other hand, terrorism can cross over the national boundary and it may be directed against one’s own or other countries.
(b) Insurgency is generally operated with the support of a section of the local people, whereas terrorism may or may not have that support.
(c) Insurgency is a miniature and localised form of terrorism.
