A Preemptive Attack on Iran's Nuclear Facilities: Possible Consequences
Quicktabs: Citation
With regard to Iran, there is no reason to believe that an attack on the facilities in Bushehr, Arak, or Natanz would have any different consequence than the Osirak example. Such an attack would likely embolden and enhance Iran's nuclear prospects in the long term. In the absence of an Iranian nuclear weapon program, which IAEA inspectors have yet to find, a preemptive attack by the United States or Israel would provide Iran with the impetus and justification to pursue a full blown covert nuclear deterrent program, without the inconvenience of IAEA inspections. Such an attack would likely be seen as an act of aggression not only by Iran but most of the international community, and only serve to weaken any diplomatic coalition currently available against Iran.The most troubling aspect of such a scenario is that, unlike Iraq in 1981, Iran is not dependent on foreign imports for nuclear technology and already has available the raw materials, and most of the designs and techniques, required to pursue a nuclear weapons program. Iran has the necessary know-how and has already produced every stage of the nuclear fuel cycle.[31] Furthermore, Iran has uranium mines in Yazd and is in the process of constructing milling plants to manufacture yellow cake uranium and conversion plants that convert it to UF6 gas.[32] Iran has also begun manufacturing its own gas centrifuges used to enrich uranium. Even if Natanz, Arak, and Bushehr were destroyed in a preemptive strike, Iran probably has duplicate equipment that can be activated and has the know-how to produce more, to pursue a more vigorous and unabated nuclear weapons program in the long term.
Contrary to popular belief, it appears that Israel's attack on Osirak in June of 1981 did nothing to hinder Iraq's nuclear aspirations. Although it temporarily set back its capabilities, it served rather to reinforce and increase Saddam's desire for a nuclear arsenal. In fact, Iraqi nuclear scientist Imad Khadduri claims that Israel's preemptive strike against the French-built Tamuz Iraqi nuclear reactor, which was not really suitable for plutonium production anyway, had the exact opposite effect of the one intended: it sent Saddam Hussein's A-bomb program into overdrive and convinced the Iraqi leadership to initiate a full fledged nuclear weapons program immediately afterwards.[28]Khidir Hamza, another Iraqi nuclear scientist and one of the leading proponents of Operation Iraqi Freedom and the overthrow of Saddam Hussein, gave a near identical assessment. He told Mike Begala on CNN's Crossfire on February 7, 2003:<blockquote>Israel -- actually, what Israel [did] is that it got out the immediate danger out of the way. But it created a much larger danger in the longer range. What happened is that Saddam ordered us - we were 400... scientists and technologists running the program. And when they bombed that reactor out, we had also invested $400 million. And the French reactor and the associated plans were from Italy. When they bombed it out we became 7,000 with a $10 billion investment for a secret, much larger underground program to make bomb material by enriching uranium. We dropped the reactor out totally, which was the plutonium for making nuclear weapons, and went directly into enriching uranium.... They [Israel] estimated we'd make 7kg of plutonium a year, which is enough for one bomb. And they get scared and bombed it out. Actually it was much less than this, and it would have taken a much longer time. But the program we built later in secret would make six bombs a year.</blockquote>Furthermore, in his book Saddam's Bombmaker, Dr. Hamza states that following the destruction of Osirak in June 1981, Saddam Hussein decided not to repeat the mistake of concentrating all of Iraq's nuclear assets in a single declared location. With the help of the Soviets, the Iraqis embarked on a covert nuclear program that simultaneously extended and hid Iraq's uranium enrichment facilities. Many of these facilities were disguised as warehouses or schools; others were hidden behind farmhouses - all of which was aimed at confusing the IAEA inspectors and preventing them from discovering Iraq's true nuclear potential.
So far, Iran and its allies in the region have encouraged the Iraqi Shi'a to continue to show restraint and work for social stability in post-war Iraq, even in the face of what would otherwise be deemed egregious provocations, such as the bombing of Shi'a holy sites in Karbala, Najaf, and Baghdad that killed hundreds of Shi'a, including dozens of Iranian pilgrims. Many in Iran have reasoned that they will benefit greatly from a stable Iraq ruled by a Shi'a government, which will necessarily be closer to Iran by virtue of shared religious and historical affiliations. However, in the event of an attack on Iran, this calculus would likely yield to a desire for revenge. In such a scenario, Iranian Revolutionary Guards could cross the border in great numbers to promote a full-blown guerrilla war against the large U.S. presence in Iraq. Iranian intelligence agents, who are currently in Iraq in significant numbers, could provoke clashes between the U.S. forces and Shi'a majority, precipitating a general uprising against Coalition forces in Iraq. It is important to note that, unlike the foreign Salafi Jihadi fighters (a la Abu Musab al Zarqawi and his Tawhid network) who infiltrated Iraq to fight the Americans and are despised by the Iraqi Shi'a, Iranian infiltrators in Iraq are likely to be seen by Iraqi Shi'a in a very different light.
