In its final report on aggression and the use of force, the International Law Association opined that the only way in which unilateral humanitarian intervention could possibly be seen as a legal exception to the prohibition of the use of force is if State practice and opinio juris were to be found establishing its status as an additional exception in customary international law. After the airstrikes conducted by the US, the UK, and France against Syria in April 2018, which took place in reaction to unprecedented usage of chemical weapons against civilian population by regime of Bashar Asad, some States and part of scholars argued that this permissive rule (exception) has already crystalized and humanitarian intervention became part of international law.
