The future of U.S. and Russian nuclear cruise missiles is at an inflection point.
As efforts intensify to bring the Iran nuclear negotiations to a successful conclusion by November 24, the issue of breakout continues to occupy center stage.
As negotiators prepare to resume talks over Iran's nuclear program, they face a formidable task: to bridge the remaining gaps and reach a comprehensive nuclear deal by November 24.
The international community has been acutely concerned for many years about Iran's increasing capacity to produce material for nuclear weapons. With sufficient fissile material and a warhead design, Iran could use its existing ballistic missiles to pose a credible nuclear threat throughout the region. Consequently, after repeatedly directing Iran to suspend uranium enrichment, the UN Security Council decided in 2010 that Iran also had to halt all activities related to ballistic missiles capable of delivering nuclear weapons.
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 exclusion poses 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.
