Threat Assessment Briefs
Threat Assessment Briefs are provided as part of the "Realistic Threat Assessments and Responses Project" led by ACA Senior Fellow Greg Thielmann. Each brief takes an objective look at key security threats, and considers policy responses to those threats.

As negotiations are poised to resume between Iran and the six powers seeking to rein in Iran's nuclear program, it is difficult to avoid a sense of déjà vu.

Preventing the production and accumulation of fissile material is an important objective of nuclear nonproliferation efforts. Unfortunately, the nuclear Nonproliferation Treaty (NPT) exempts the fuel used in naval propulsion reactors from the constraints the treaty otherwise applies to enriching uranium beyond the levels used in civilian power reactors. As the number of countries with nuclear-powered submarines expands, this exclusionposes a growing risk to achieving the nonproliferation goals of the treaty.

Following condemnations by the international community of North Korea’s December satellite launch and February nuclear test, Pyongyang unleashed a furious barrage of rhetorical threats in March and April against the United States and South Korea. Now, the hot air war of the early spring appears to be over, despite the exercise launch of six short-range missiles by North Korea off its east coast in recent days and the ongoing visit of a U.S. aircraft carrier strike group to South Korea.

Ten years ago today, President George W. Bush said in a radio address to the nation: "It is clear that Saddam Hussein is still violating the demands of the United Nations by refusing to disarm." Eleven days later, he announced the invasion of Iraq to remove the weapons of mass destruction (WMD) allegedly possessed by Hussein's brutal regime and to prevent their use by or transfer to terrorist networks such as al Qaeda. That no such weapons existed was less a symptom of flawed intelligence than the U.S. leaders' obsession with achieving regime change in Baghdad and their consequent willingness to distort evidence on WMD toward that end.

Although plans for expanding U.S. strategic missile defenses focus on the Iranian ICBM threat, that threat is not emerging as was previously predicted. Iran conducted no long-range ballistic missile tests in 2012 and has not flown even the larger space launch vehicle that it displayed two years ago, which could have helped advance ICBM technology. Moreover, Tehran has still not decided to build nuclear weapons and continues to focus on short- and medium-range rather than longer-range ballistic missiles.

Since President Barack Obama took office four years ago, diplomats from the P5+1 group of states (China, France, Russia, the United Kingdom, the United States and Germany) and Iran have engaged in renewed but intermittent discussions aimed at resolving concerns about Iran's nuclear program. So far, however, the two sides have been unable to reach an agreement that would bridge the differences between the proposals that have been exchanged during the talks.

The new quarterly report from the International Atomic Energy Agency (IAEA) on Iran’s nuclear program finds that Tehran has continued to install more centrifuges for uranium enrichment at its underground complex at Fordow, although the total number of operating centrifuges at Fordow has not yet increased, according to the Agency

A long submerged flaw in the nuclear Non-Proliferation Treaty (NPT) surfaced conspicuously in June when Iran announced it intended to build a nuclear-powered submarine. The treaty does not ban a non-nuclear weapons state's production of weapons-grade uranium if it is to be used to power a naval reactor.

On June 19, Iran concluded the third round of talks on its nuclear program in as many months, this time in Moscow, with senior officials of the six powers - the United States, the United Kingdom, France, Germany, Russia, and China. Although there were strong incentives for the six to secure limits on Iran's most worrisome stockpiles of enriched uranium and for Iran to avoid an impending tightening of economic sanction, no breakthrough was achieved by the end of the latest round. But neither did diplomatic dialogue come to an end.

North Korea's failed attempt to launch a satellite from its Unha-3 space rocket on April 13 and India's successful flight test of the Agni-5 long-range missile on April 19 marked significant events in the ballistic missile development programs of the two countries. These two ballistic missile test events not only reveal technical information about system performance, but also invite reflection on U.S. policy responses.
