After Obama’s Nuke Deal, What Happens If Israel Attacks Iran?

In urging congressional Republicans and Israeli Prime Minister Benjamin Netanyahu to reconsider their strong opposition to a new international agreement to block Iran’s development of a nuclear weapon in return for lifting economic sanctions, President Obama on Wednesday argued opponents of the deal have offered no alternative to diplomacy except going to war in the Middle East.

"Israel has legitimate concerns about its security regarding Iran," Obama said at a White House news conference, referring to Israeli leaders' repeated concerns about Iran's sponsorship of Hezbollah and repeated calls for the destruction of Israel. However, Obama noted that these threats would be exacerbated if Iran obtains nuclear weapons, and Netanyahu has yet to present a better “Plan B.”

“Without a deal,” the president said, "there would be no limits to Iran's nuclear program and Iran could move close to a nuclear bomb. Without a deal, we risk even more war in the Middle East."

But what would happen if Netanyahu made good on his threat to launch a preemptive military strike to take out Iran’s nuclear plants? If he concluded that the very survival of the Jewish state were at stake? How would the United States — Israel’s closest and staunchest ally — respond to such an attack with so much invested in a diplomatic solution to the Iranian nuclear threat in the Middle East?

It was a question that hung in the air during Obama’s lengthy news conference but one that was neither asked nor answered. Experts differ on how the U.S. might respond to such an action, but most doubt Israel would take such an action that would leave it virtually isolated on the world stage.

“If you see a bunch of Iranian physicists disappearing or things mysteriously self-destructing [in Iranian nuclear facilities], I wouldn’t be surprised,” said a former Obama administration official who worked on Middle East issues. “But the idea of Israelis strapping into a cockpit and flying off and bombing Iranian targets, I think that’s science fiction and also fantasy fiction.”

Netanyahu and other critics of the deal insist that it would only temporarily prevent Iran from building a nuclear weapon. In addition, they warned that the Islamic country, which has long called for “death” to the United States and Israel, would reap hundreds of billions of dollars in new oil revenues and other funds once onerous international economic sanctions are lifted by the end of the year.
