In the 21st Century the problem is not to allow the use of Chemical & Biological Weapons & 'maybe' just 'maybe' achieve total nuclear disarmament (not in the next 120 years) It's not just the responsibility of the UK, USA, & France but that of every country that's a signatory of the conventions that banned the use of such weapons to intercept and retaliate against members that use such kind of weapons. From Kenya, Ghana, South Africa, Brazil, China, India , Afghanistan, Butan, Taiwan, Iceland should use heavy force to stop the use of such weapons.
