Israel has warned relentlessly against a nuclear deal with Iran, but experts say Prime Minister Binyamin Netanyahu's options are limited and immediate military action is unlikely. Netanyahu slammed Thursday's announcement by US President Barack Obama on the framework of a deal allowing the Islamic regime to continue enriching uranium at limited amounts, saying that if implemented it would jeopardize the Jewish state's very existence, reports AFP . "PM Netanyahu to Pres Obama: A deal based on this framework would threaten the survival of Israel," Netanyahu spokesman Mark Regev wrote on his official Twitter account, citing a late night telephone conversation between the two. Regev quoted the premier as saying that the deal as it appears to be emerging "would not block Iran's path to the bomb. It would pave it. ...It would increase the risks of nuclear proliferation and the risks of a horrific war." Israel is the Middle East's sole nuclear power, which has not declared its nuclear power in the hopes of avoiding a nuclear arms race. Repeating previous Israeli warnings, Intelligence Minister Yuval Steinitz said Thursday that all options were open, stating "if we have no choice, we have no choice...the military option is on the table." Nevertheless, analysts said it was tough diplomacy and not military strikes that would be the focus of Israeli efforts after Thursday's announcement, at least in the short term. "After the entire world signed an agreement with Iran, I don't see Israel striking Iran nuclear facilities tomorrow morning," said Yoel Guzansky, the former head of the Iran desk at Israel's National Security Council. "It will be seen as jeopardising global security," he said. "However if the Iranians were caught cheating, then it's a different ball game, then you have the legitimacy to do other things." Under the framework, nuclear-related US and EU sanctions against Iran will be lifted once the UN atomic watchdog has verified that Tehran has implemented its promises. Yossi Kuperwasser, until recently the director general of Israel's strategic affairs ministry, said Netanyahu would be seeking to keep up pressure right up until a final accord, which is due to be drafted by the end of June. Netanyahu should "keep the military option on the table. Not only the military option - keep doing whatever is necessary to prevent Iran from having the nuclear capability," Kuperwasser said. "Iranians will be careful" Discussion of an Israeli military attack on Iran's nuclear facilities peaked in 2011-2012, when Ehud Barak was defense minister and Netanyahu premier. But Kuperwasser said talk of an attack does not necessarily translate into action. "As long as you have a credible military option, the Iranians will be very careful to not put you in a position where you will have to use it," he said. Emily Landau, an expert on nuclear strategy and arms control at the Institute for National Security Studies in Tel Aviv, said Israel is limited in what it can do in the face of what it considers to be a bad deal. "It breaks down to attempts to convince" the world powers negotiating with Iran to reach a better agreement, she said. "This is what it's been doing the whole time, and will continue doing with greater vigor." She said that Netanyahu's recent statements have been less focused on military options. "There is definitely a change in the nuance, the rhetoric has changed," she said. "We no longer hear these insinuated threats of a military attack (on Iran's nuclear facilities) from Netanyahu."
