The Chemical Weapons Convention (CWC) is one of the most successful international agreements. With 192 States Parties having committed to eliminating chemical weapons and preventing any return to chemical warfare, the Convention has achieved near-universal status.
Now, more than ever, the States Parties must push for universalization, since there can be no justification for remaining outside this Convention. The ICRC joins calls for the remaining five States the Democratic People's Republic of Korea, Israel, Egypt, Palestine and South Sudan to ratify or accede to it without delay.
The Convention's comprehensive prohibition of an entire class of weapons is firmly rooted in the age-old taboo against the use of poison as a means of warfare. Today, the prohibition of the use of chemical weapons enshrined in the 1925 Geneva Protocol and the CWC is a rule of customary international humanitarian law. It is binding on all parties to all armed conflicts, be they States or non-State armed groups. The ban is absolute and far-reaching, covering both improvised and classical chemical weapons.
