Cunha, Bouvet Island 2,500 km southwest from Cape Town, the Crozet Islands 2,350 km south of Madagascar, Kerguelen, or Île Amsterdam and Île Saint-Paul, which, (with American Samoa in the Pacific Ocean), are the only Southern Hemisphere lands not in any of the Nuclear-Weapon-Free Zones. History The quest for a nuclear free Africa began when the Organization of African Unity formally stated its desire for a Treaty ensuring the denuclearization of Africa at its first Summit in Cairo in July 1964. The Treaty was opened for signature on 11 April 1996 in Cairo, Egypt. All the States of Africa are eligible to become parties to the Treaty, which will enter into force upon its 28th ratification; the Protocols with also come into force at that time for those Protocol signatories that have deposited their instruments of ratification. It was reported in 1996 that no African Arab state would ratify the Treaty until Israel renounces its nuclear weapons program. However, Algeria, Libya, and Mauritania have since ratified the Treaty. The United Nations General Assembly has passed without a vote identical resolutions in 1997 (twice), 1999, 2001, 2003, and 2005 calling upon African States that have not yet done so to sign and ratify the Treaty as soon as possible so that it may enter into force without delay, and for States contemplated in Protocol III to take all necessary measures to ensure its speedy application. A resolution had been passed in 1995 in support of the final text of the Treaty. Ratified or acceded states As of May 2022, the Treaty has been ratified by 43 states and the Sahrawi Arab Republic, and entered into force on 15 July 2009.
