Action Against Host States of Terrorist Groups
This chapter examines the problems that could arise when a state invokes self-defence to justify action against terrorist groups in another state. It first considers indirect armed attack against armed groups and the controversy surrounding the use of self-defence where armed groups are controlled by a foreign state, with particular reference to the International Court of Justice (ICJ) jurisprudence. It then discusses the possibility that an armed attack could occur, permitting a forcible response in the context of international law, without attribution to a state by citing the Nicaragua case in which the ICJ pronounced that self-defence is permissible against a host state in effective control of an armed group. The chapter also looks at the case of Afghanistan and its relationship to Al Qaeda as an example of a state’s claims of self-defence against terrorism.
