JERUSALEM, Israel -- Israeli Strategic Affairs Minister Moshe Ya'alon said the military option against Iran must remain viable if sanctions fail.
"Tight sanctions must continue, alongside international isolation, support for the opposition and a credible military option," the former IDF chief of staff said in an interview with Israel's Walla news.
"[The] military option can be prevented if all the other measures are taken," Ya'alon said, but Israel will not rest "until the centrifuges in Iran stop spinning."
Israeli Foreign Minister Avigdor Lieberman remains skeptical about reaching an agreement with Iran on its nuclear ambitions.
"While sanctions on Iran have an impact, it is not enough of an impact to bring a real chance in the situation," Lieberman said. "We should also pay attention to the negative Iranian involvement in every possible place in the Middle East," Lieberman added.
Meanwhile, Iranian Foreign Minister Ali Akbar Salehi told reporters in Tehran Tuesday that Iran would not cave in to international pressure.
"Their policies of pressure and intimidation are futile," Salehi reportedly said. "They have to adopt policies to show goodwill to solve this issue."
In a report to be released Friday, the International Atomic Energy Agency (IAEA) says Iran has installed 350 new centrifuges in its Fordow underground facility near Qom since February, which has further enhanced its uranium enrichment capabilities.
