Argument

Containment Breach

Preventing nuclear war between Iran and Israel would be more difficult than it ever was to avoid a nuclear confrontation between the United States and the Soviet Union. Here's why.

A number of influential policymakers and foreign policy analysts appear much too complacent regarding the prospects of a nuclear-armed Iran. Former CENTCOM Commander Gen. John Abizaid has argued that "[d]eterrence will work with Iran," and former Deputy Director of National Intelligence Thomas Fingar, one of the authors of the 2007 National Intelligence Estimate on Iran's nuclear capabilities, has voiced similar opinions.

Deterrence in the Middle East, they argue, could be just as stable as it was between the United States and the USSR during the Cold War. "Israel's massive nuclear force will deter Iran from ever contemplating using or giving away its own (hypothetical) weapon," wrote Fareed Zakaria in the Oct. 12 edition of Newsweek. "Deterrence worked with madmen like Mao, and with thugs like Stalin, and it will work with the calculating autocrats of Tehran."

But this historical analogy is dangerously misconceived. In reality, defusing an Israeli-Iranian nuclear standoff will be far more difficult than averting nuclear war during the Cuban missile crisis. This is true even if those Iranians with their fingers on the nuclear trigger are not given to messianic doomsday thinking. Here are five factors that will make an Israeli-Iranian nuclear confrontation potentially explosive.

Communication and trust. The October 1962 negotiations that settled the Cuban missile crisis were conducted through a fairly effective, though imperfect, communication system between the United States and Russia. There was also a limited degree of mutual trust between the two superpowers. This did not prevent confusion and suspicion, but it did facilitate the rivals' ability to understand the other's side and eventually resolve the crisis.

Israel and Iran, however, have no such avenues for communication. They don't even have embassies or fast and effective back-channel contacts -- and, what's more, they mistrust each other completely. Israel has heard Iranian leaders -- and not just President Mahmoud Ahmadinejad -- call for its destruction. Meanwhile, Iranian leaders remain prone to paranoid and conspiratorial views of the outside world, especially Israel and the United States. In any future Iranian-Israeli crisis, each side could easily misinterpret the other's moves, leading to disaster. A proxy war conducted by Iran through Hezbollah or Hamas against Israel could quickly lead to a series of escalating threats.

Goals. The Soviets wanted to extend their power and spread Communism -- they never pledged the annihilation of America. Iranian leaders, however, have called for Israel to be "wiped off the map of the Middle East." After the street protests that followed the June presidential election, Iran has entered into chronic instability. In a moment of heightened tension and urgent need for popular support, an Iranian leader could escalate not only rhetoric but action.

There is a strong precedent in the Middle East of such escalation leading to war. Arab threats to destroy any Jewish state preceded a massive invasion of the new Israeli state in May 1948. In May and June 1967, Egypt's President Gamal Abd al-Nasser loudly proclaimed his intent to "liberate Palestine" (i.e. Israel in its 1949 borders), and moved his panzer divisions to Israel's border. The result was the Six Day War.

Command and control. In 1962, the two superpowers possessed sophisticated command-and-control systems securing their nuclear weapons. Both also employed effective centralized decision-making systems. Neither may be the case with Iran: Its control technology will be rudimentary at first, and Tehran's decision-making process is relatively chaotic. Within Iran's byzantine power structure, the Islamic Revolutionary Guard Corps (IRGC) mounts an army and navy of its own alongside the regular army and navy, and internal differences within the regime over nuclear diplomacy are evidence of conflicting lines of authority. Recent events suggest that the IRGC, allied with Ahmadinejad, has increasingly infringed on the authority of the supreme leader, Ayatollah Ali Khamenei. As a result, no one can be certain how decisions are made and who makes them.

Mutual deterrence. Both the United States and USSR had second-strike capability made credible by huge land masses. They possessed hardened missile silos scattered throughout the countryside, large air forces equipped with nuclear bombs, and missile-launching submarines. In the Middle East, Iran stretches across a vast 636,000 square miles, against Israel's (pre-1967) 8,500 square miles of territory. This point was made by ex-president Hashemi Rafsanjani in 2001, who noted, "Israel is much smaller than Iran in land mass, and therefore far more vulnerable to nuclear attack." If this is the way an Iranian pragmatist thinks, how are the hard-liners thinking?

In contrast, by 1962, the two superpowers implicitly recognized the logic of mutually assured destruction. And yet, they still came relatively close to war -- in John F. Kennedy's words, the risk of a nuclear conflict was "between one out of three and even." When Iran goes nuclear, the huge disparity in size will pose a psychological obstacle for its recognition of mutual deterrence. Even assuming the United States promises Israel a retaliatory nuclear umbrella, Iran will doubt U.S. resolve. The mullahs will be tempted to conclude that with Israel gone, the United States would see no point in destroying Iran. Given the criticism leveled today against President Harry Truman for using the bomb against Japanese civilians in World War II, what are the chances of American retaliation against Iran, especially if the Islamic Republic has not attacked the United States?

Crisis instability. In view of the above dangers, if and when a grave crisis does erupt, Israel would be tempted to strike first in order to prevent an Iranian nuclear attack, which would devastate its urban core. Iran will be well aware of Israel's calculations and, in the early years of becoming a nuclear power, will have a smaller and probably more vulnerable nuclear arsenal. This will give it, in turn, strong incentives to launch its own preemptive strike.

The implications of a nuclear-armed Iran go well beyond the risks of an Iranian-Israeli war. Once Iran is a nuclear power, the Middle East is likely to enter a fast-moving process of nuclear proliferation. Until now, most Arab governments have not made an effort to match Israel's  nuclear arsenal. However, they perceive Iran's nuclear weapons as a real strategic threat. A Middle East where more and more states have nuclear arms, known to experts as a saturated multiplayer environment, will present an almost insurmountable challenge for deterrence calculations by regional or external powers, and a still greater risk of serious instability. Contrary to the wishful thinking of some analysts that the possession of nuclear weapons could make Iran more cautious, a nuclear Iran will likely be emboldened. It could press Hezbollah to be more aggressive in Lebanon, flex its muscles in the Persian Gulf, and step up its challenges against U.S. forces in the region.

If diplomacy and sanctions fail to prevent Iran from going nuclear, Israel will be caught on the horns of an acute existential dilemma not of its own making. If Israel does not act, it will face a future in which it will live under a nuclear sword of Damocles wielded by a state that has called for its destruction. If it does act in the face of what are, after all, probabilities rather than certainties, Israel must expect a serious conventional war that would include attacks from Iran's proxies Hamas and Hezbollah and an escalation in international terrorism, all in exchange for an uncertain degree of success. Contrary to the assessments of those who foresee a best case scenario of stable deterrence, , a nuclear-armed Iran will usher in a new era of instability in the Middle East -- with consequences that nobody can accurately predict, much less contain.
