There is no consensus, scholarly or legal, on the definition of terrorism.[1][2][3]
Various legal systems and government agencies use different definitions of terrorism, and governments have been reluctant to formulate an agreed-upon legally-binding definition. Difficulties arise from the fact that the term has become politically and emotionally charged.[4][5] A simple definition proposed to the United Nations Commission on Crime Prevention and Criminal Justice (CCPCJ) by terrorism studies scholar Alex P. Schmid in 1992, based on the already internationally accepted definition of war crimes, as "peacetime equivalents of war crimes",[6] was not accepted.[7][8]
Scholars have worked on creating various academic definitions, reaching a consensus definition published by Schmid and A. J. Jongman in 1988, with a longer revised version published by Schmid in 2011,[8] some years after he had written that "the price for consensus [had] led to a reduction of complexity".[9]The Cambridge History of Terrorism (2021), however, states that Schmid's "consensus" resembles an intersection of definitions, rather than a bona fide consensus.[10]
The United Nations General Assembly condemned terrorist acts by using the following political description of terrorism in December 1994 (GA Res. 49/60):[11]
Criminal acts intended or calculated to provoke a state of terror in the general public, a group of persons or particular persons for political purposes are in any circumstance unjustifiable, whatever the considerations of a political, philosophical, ideological, racial, ethnic, religious or any other nature that may be invoked to justify them.
