Briefing
There is no clear answer to the question of whether it is legal for states to use force against Iran. It depends largely on your view of whether Iran is about to use nuclear weapons. Military force is legal under international law in only three circumstances: the most likely to apply in this situation is self-defence, but even then purely preventive force is not allowed.
