The New Loose Nukes

LOS ANGELES – Nobody would dispute the danger inherent in possessing nuclear assets. But that danger becomes far more acute in a combat zone, where nuclear materials and weapons are at risk of theft, and reactors can become bombing targets. These risks – most apparent in today’s chaos-ridden Middle East – raise troubling questions about the security of nuclear assets in volatile countries everywhere.

Two recent events demonstrate what is at stake. On July 9, the militant group now known as the Islamic State captured 40 kilograms (88 pounds) of uranium compounds at Mosul University in Iraq. The captured uranium was not weapons-grade; international inspectors removed all sensitive material from Iraq following the 1991 Gulf War (which is why it was absent when the United States invaded in 2003). But what international response, if any, would have been initiated if the cache had been highly enriched?

On the same day, Hamas launched three powerful Iranian-designed rockets from Gaza at Israel’s Dimona reactor. Luckily, two missed the target, and Israel managed to intercept the third. But the episode represented a serious escalation of hostilities and served as an important reminder of the vulnerability of nuclear reactors in warzones.

In fact, Hamas made similar attempts to attack the Dimona complex in 2012, as did Iraq in 1991, with the aim of releasing the site’s contents to inflict radiological damage on Israel’s population. (The perpetrators appeared clueless to the fact that certain weather conditions would have concentrated the radioactive debris in the Palestinian-majority West Bank.)
