Benjamin Netanyahu is demanding increase in pressure on Iran, so that Iran halts all enrichment of uranium. Enrichment of Uranium is a key step in producing a nuclear weapon.
Iran must remove its stockpile of enriched uranium from the country; it must close suspicious enrichment facilities and shut down a facility that could produce plutonium. Plutonium is another potential gateway to production of nuclear arms. Israel considers a nuclear-armed Iran a threat to its very survival.
