William Boothby joins The Fourth Leg's Philip Reiner and Peter Hayes for a discussion of the legal limits surrounding the use of nuclear weapons.

Article 2(4) of the UN Charter applies to nuclear weapons as it does to conventional uses of force. Likewise, an armed attack giving rise to the right to use force in self defense might take the form of a nuclear strike. But it is the scale and effects of the nuclear strike that will determine its classification as a use of force and armed attack.
