JERUSALEM - Israeli Defense Minister Ehud Barak on Dec. 1 ruled out a strike against Iran's nuclear facilities "for the moment," in remarks to public radio, but said that the Jewish state would keep all options open.
"We have no intention of acting for the moment ... We should not engage in war when it is not necessary, but there may come a time or another when we are forced to face tests," Barak said.
"Our position has not changed on three points: a nuclear Iran is unacceptable, we are determined to stop that, and all options are on the table," he added.
Israel and much of the international community fears that Iran's nuclear program masks a drive for a weapons capability. Tehran denies any such ambition and says the program is for peaceful civilian energy and medical purposes only.
Israel has pushed Washington and the EU for tough sanctions against Tehran, but warned that it would not allow Iran to obtain nuclear weapons, and that military action to stop the program remained an option.
Barak said he was confident that military action against Iran would not be devastating for Israel.
"War is not a picnic, but if Israel is forced to act, we won't have 50,000, 5,000 or even 500 dead, so long as people stay in their homes," he said, noting that rockets fired at Israel by Iraq during the 1991 Gulf War had not killed a single Israeli.
Asked about potential differences between the United States and Israel on tactics to stop Iranian nuclear development, Barak stressed that the Jewish state would ultimately take the decisions it thought best.
"It must be understood that Israel is sovereign. The government, the army and the security services are the only ones responsible for the security and the existence of Israel," he said.
Barak declined to comment on what was behind at least two explosions in Iranian cities in recent weeks, only one of which has been confirmed by Iranian authorities.
"Anything that sets back the Iranian nuclear program, whether it is accidental or the product of other methods, is welcome," he said, refusing to say whether Israeli forces had any role in the incidents.
On Nov. 28, Brig. Gen. Itai Brun, head of research for Israeli military intelligence, told lawmakers that Iran was "using 6,000 centrifuges regularly, out of 8,000 installed."
"Until today, they have managed to accumulate approximately 50 tons of low enriched uranium, and a bit less than 100 kilos of 20 percent enriched uranium," he said.
Brun said Iran would need at least 220 kilos of 20 percent enriched uranium if it decided on a drive for the much higher levels of enrichment necessary to produce a nuclear weapon.
On Nov. 29, the former head of Israeli military intelligence, Amos Yadlin, said he estimated Iran has "enough material for four to five bombs."
But he said Tehran could not immediately assemble a nuclear weapon, if that was their goal.
"Once they decide they want to, it will take them a year to 18 months to attain a bomb," he said.
