| Eight countries—China, France, India, North Korea, Pakistan, Russia, the United Kingdom, and the United States—have openly declared that they possess nuclear weapons. Israel is widely believed to have nuclear weapons. Iran has demonstrated the ability to enrich uranium for use in nuclear power plants but denies that it has a nuclear weapons program. A U.S. intelligence estimate issued in 2007 concluded that Iran had a nuclear weapons program but abandoned it in 2003. In the past, governments in Argentina, Australia, Brazil, Iraq, Libya, Romania, South Korea, Sweden, Switzerland, Taiwan, and Yugoslavia had active programs to develop nuclear weapons but abandoned those programs. Only one country, South Africa, ever developed nuclear weapons and then eliminated them. |
