Studying About International Responsibility of States for Measures of Terrorist Groups

The responsibility of state for measures of terrorist groups is a challenging question. Considering all articles of the ILC Draft Articles on State Responsibility for International wrongful Acts can not include all aspects of co-operation between state and terrorist groups. Relation between state and terrorist groups is in three forms: first, terrorist groups are under control or instruction of state. Second, terrorist groups are independent from state and states only co-operate with and assist them. Third, states are indifferent to measures of terrorist groups done in their territory against other states. Draft Articles of Responsibility of States for International Wrongful Acts enacted in 2001 only respond to the first situation and there is a gap in other situations. Many opinions have been presented for filling this gap which include Theory of absolute or collective responsibility, Theory of Complicity, Condonation and accounting of damage theory and Theory of causation-based responsibility. In this article, it will be tried to study each of these theories and their weakness and strength points and to present final solution.
