JERUSALEM (JTA) — Israeli Prime Minister Benjamin Netanyahu will discuss stopping Iran’s nuclear program during a meeting with President Obama.

Netanyahu will meet with Obama later this month during the United Nations General Assembly, he told his Cabinet on Tuesday.

Until Iran actually stops its nuclear program “the pressure on Iran must be increased and not relaxed, and certainly not eased,” Netanyahu said.

The German newspaper Der Spiegel reported Monday that Iran is willing to close its uranium enrichment facility at Fordo under international supervision in return for an easing of Western sanctions. In addition, U.S. officials have suggested that the Obama administration would be willing to ease or lift some sanctions on Iran in return for progress in talks on stopping Iran’s nuclear program.

Netanyahu outlined four steps needed in order to call Iran’s nuclear program stopped: halting all uranium enrichment; removing all enriched uranium; closing Fordo; and stopping plutonium enrichment.

He reiterated that “Israel must continue to build up its strength so that it will always be able and ready to defend itself by itself against any threat.”

Netanyahu and Obama also are expected to discuss during their meeting the threat of Syrian chemical weapons.
