Geneva Convention

Aside from the UN Charter, the Geneva Conventions are among the most widely ratified international agreements. The four 1949 Geneva Conventions were ratified, in their entirety or with reservations, by 196 countries. Much of the international humanitarian law contained in the Geneva Conventions has become customary international law, and therefore would apply to all states and non-state armed groups, even those that are not a party to the Geneva Conventions. The legal obligations created under the Geneva Conventions are somewhat different from other international treaties in that a breach of the Geneva Conventions by one party does not furnish a directly affected party with the option to cease complying with its treaty obligations.
