Israel and weapons of mass destruction

Nuclear weapons and Israel

It is believed that Israel had possessed an operational nuclear weapons capability by 1967, with the mass production of nuclear warheads occurring immediately after the Six-Day War. Although no official statistics exist, it has been estimated that Israel possesses from 75 to as many as 400 nuclear weapons, which are reported to include thermonuclear weapons in the megaton range.

Israel is also reported to possess a wide range of different systems, including neutron bombs, tactical nuclear weapons, and suitcase nukes. Israel is believed to manufacture its nuclear weapons at the Negev Nuclear Research Center.

Chemical weapons

Israel has signed but not ratified the Chemical Weapons Convention (CWC). There are speculations that a chemical weapons program might be located at the Israel Institute for Biological Research (IIBR) in Ness Ziona.[

In 1993, the U.S. Congress Office of Technology Assessment WMD proliferation assessment recorded Israel as a country generally reported as having undeclared offensive chemical warfare capabilities. Former US deputy assistant secretary of defense responsible for chemical and biological defense, Bill Richardson, said in 1998 "I have no doubt that Israel has worked on both chemical and biological offensive things for a long time ... There's no doubt they've had stuff for years.
