This Commentary on the Convention on Cluster Munitions is a detailed assessment of the negotiation, content, and implications of the Convention, which is the latest treaty to ban a conventional weapon. The treaty, which will enter into force as binding international law on 1 August 21, bans the production, stockpiling, transfer, and use of all cluster munitions. The book describes what cluster munitions are, when and where they have been used, and what steps States Parties will need to consider in order to implement the treaty's provisions. The Commentary goes systematically through the Convention article by article, explaining the purpose of each provision, its background and negotiation, and the meaning of each paragraph and sub-paragraph.
