Will Obama Make Good on His Promise to Reduce the Threat of Nuclear Warfare?


As President Obama prepares for his final State of the Union address tonight, there's one critical issue he has neglected over the last few years that bears revisiting: the nuclear threat, which—along with climate change—poses the biggest risk to the future of the planet.

Fortunately, there are a number of things the president can still do to strengthen international security that would not require him to go through Congress or negotiate with Russia. And taking such executive action would not be out of the ordinary. Indeed, Obama's Republican predecessors, George H.W. Bush and George W. Bush, both made significant unilateral cuts in the U.S. nuclear arsenal.

As President Obama prepares for his final State of the Union address tonight, there's one critical issue he has neglected over the last few years that bears revisiting: the nuclear threat, which—along with climate change—poses the biggest risk to the future of the planet.

According to Stephen Young, a senior analyst at the Union of Concerned Scientists (UCS), Obama could begin tonight by making four related announcements about U.S. nuclear policy. First, he could declare that the U.S. will take its land-based nuclear missiles off hair-trigger alert, abandoning a dangerous, outdated Cold War policy that increases the possibility of an accidental nuclear launch. Second, he could cancel a proposed new nuclear-armed cruise missile that would likely lower the threshold for using nuclear weapons. Third, he could cut U.S. deployed strategic nuclear warheads by a third. And fourth, he could declare that the sole purpose of U.S. nuclear weapons is to deter a nuclear attack on the U.S. and its allies, which would fulfill his promise to reduce the role such weapons play in U.S. policy.

None of these steps would compromise U.S. security. On the contrary, they would not only save U.S. taxpayers hundreds of billions of dollars, they would also make the U.S.—and the rest of the world—a much safer place.

Obama's Promising Start

President Obama actually addressed the nuclear issue right out of the starting gate. Just a few months after taking office, he gave a widely acclaimed speech in Prague on reducing the threat posed by nuclear weapons. "The existence of thousands of nuclear weapons is the most dangerous legacy of the Cold War," he said. "And as the only nuclear power to have used a nuclear weapon, the U.S. has a moral responsibility to act. We cannot succeed in this endeavor alone, but we can lead it, we can start it." He then cited some of the "concrete steps" the U.S. would take "toward a world without nuclear weapons."

A year later, in April 2010, he was back in Prague to follow through with one of his promised concrete steps: to sign the New Strategic Arms Reduction Treaty (New START) with Russia, further cutting both countries arsenals and reinstituting a strict verification system that the Bush Administration had allowed to lapse. But since then, Obama has not been able to accomplish much else, despite his high hopes. In fact, it seems that his administration is going in the wrong direction. As I reported last August, it wants the U.S. government to spend $1 trillion over the next three decades on a new generation of nuclear warheads, bombers, submarines and intercontinental ballistic missiles (ICBMs).

So, let's examine Obama's options to reduce the nuclear threat a bit more carefully.

Take U.S. Land-Based ICBMs Off Hair-Trigger Alert

Since the early days of the Cold War, the U.S. has been keeping its land-based ICBMs in a state of readiness that allows them to be launched within minutes, at least in part to avoid having them destroyed by a surprise nuclear attack. At this point, however, it is highly unlikely Russia would launch a massive first strike and no other country is capable of doing so. What's more likely is an accidental, erroneous or unauthorized ICBM launch in response to a false attack warning, triggered either by a technical glitch or a human error. In fact, there have been a number of incidents of both kinds in Russia and the U.S. over the last few decades that could have prompted a nuclear launch.

Obama acknowledged the risks posed by this outmoded policy even before he moved into the White House. "Keeping nuclear weapons ready to launch on a moment's notice is a dangerous relic of the Cold War," Obama said in an interview published by Arms Control Today in September 2008. "Such policies increase the risk of catastrophic accidents or miscalculation. I believe that we must address this dangerous situation."

Obama is not alone in that assessment. A number of former secretaries of state and retired high-ranking military officers, including former commanders of the U.S. Strategic Command and the Navy's nuclear submarine fleet, agree.

Cancel the Long-Range Standoff Missile

The Obama Administration has proposed developing a new, stealthy nuclear-armed cruise missile, dubbed the long-range standoff (LRSO) missile, to replace the air-launched cruise missile (ALCM), which is due for retirement in 2030. The Air Force plans to buy 1,000 to 1,100 of these new missiles—roughly double the 572 ALCMs now in its stockpile—with a price tag of $20 billion to $30 billion.

The new missile would be faster, more accurate and longer-range than the current model. And that's not good, says Young, the UCS analyst. Why? Because, he says, it will make it easier for the U.S. to use nuclear weapons.

By being more "usable," the proposed LRSO missile would increase the role that nuclear weapons play in U.S. security policy by lowering the threshold for when the U.S. might consider using one. And that would signal to the rest of the world that the U.S. believes nuclear weapons retain significant war-fighting value. That's not a message the U.S. should be sending.

"The bottom line," Young says, "is the proposed missile would not enhance our security. In fact, it would do the exact opposite."

Reduce the U.S. Nuclear Arsenal by a Third

Obama should cut the 1,550 long-range nuclear weapons the U.S. currently deploys to 1,000, a third lower than the number negotiated with the Russians under the New START arms control agreement. After all, he plainly stated in a June 2013 speech that such a reduction is eminently feasible.

"After a comprehensive [Pentagon] review," Obama said during a trip to Germany, "I've determined that we can ensure the security of America and our allies and maintain a strong and credible strategic deterrent, while reducing our deployed strategic nuclear weapons by up to one-third."

According to Young, New START verification procedures would be able to substantiate such a reduction without requiring a new treaty; a smaller nuclear force would save U.S. taxpayers tens if not hundreds of billions of dollars; and, despite its aggressive actions in Ukraine, Russia would likely follow suit and reduce its arsenal, especially given its ongoing financial crisis.

"Some nuclear proponents may argue that reducing the U.S. nuclear arsenal could embolden Russia," Young says. "But cutting 1,550 deployed strategic warheads to 1,000 would have no effect on nuclear deterrence whatsoever and save resources for higher priorities."

Define the Purpose of U.S. Nuclear Weapons

In 2010, the Pentagon issued a report that defined the goals for U.S. nuclear policy, strategy, capabilities and force posture for the following five to 10 years. Called the Nuclear Posture Review, it stated: "The U.S. will continue to strengthen conventional capabilities and reduce the role of nuclear weapons in deterring non-nuclear attacks, with the objective of making deterrence of nuclear attack on the U.S. and our allies the sole purpose of U.S nuclear weapons."

Obama should make that "objective" official policy.

The Nuclear Posture Review listed "a narrow range of contingencies in which U.S. nuclear weapons may still play a role in deterring a conventional or CBW [chemical or biological weapons] attack against the U.S. or its allies and partners" for countries that either have nuclear weapons or are not in compliance with their nonproliferation agreements.

Young says that "narrow range of contingencies" is shortsighted.

"Giving nuclear weapons a role beyond deterring a nuclear attack is unnecessary and downright dangerous," he says. "Nuclear weapons don't add to the deterrence the overwhelmingly superior U.S. conventional forces already provide against a non-nuclear attack or the U.S.' ability to respond to such an attack. And if the U.S. considers nuclear weapons to be 'usable,' that could encourage other countries to try to join the nuclear club."

The U.S. should strengthen—not undermine—the international consensus against the use and proliferation of nuclear weapons. Declaring that the U.S. would use nuclear weapons only to deter a nuclear attack is one way to do that.

Obama at the Finish Line

In October 2009, President Obama was awarded the Nobel Peace Prize, largely due to his efforts to promote nuclear disarmament. Shortly after learning he had won the prize, he held a press conference in the White House Rose Garden.

"I will accept this award as a call to action, a call for all nations to confront the common challenges of the 21st century," he told reporters. "We cannot tolerate a world in which nuclear weapons spread to more nations and in which the terror of a nuclear holocaust endangers more people. And that's why we've begun to take concrete steps to pursue a world without nuclear weapons: because all nations have the right to pursue peaceful nuclear power, but all nations have the responsibility to demonstrate their peaceful intentions."

It's been more than six years since Obama made that statement and there is plenty left to do. But the president can still heed that call to action by taking a few more concrete steps before he leaves office. Tonight's State of the Union address would be a good place to start.

President Donald Trump mocked water-efficiency standards in new constructions last week. Trump said, "People are flushing toilets 10 times, 15 times, as opposed to once. They end up using more water. So, EPA is looking at that very strongly, at my suggestion." Trump asked the Environmental Protection Agency (EPA) for a federal review of those standards since, he claimed with no evidence, that they are making bathrooms unusable and wasting water, as NBC News reported.

A volcano erupts on New Zealand's Whakaari/White Island on Dec. 9, 2019. Michael Schade / Twitter

A powerful volcano on Monday rocked an uninhabited island frequented by tourists about 30 miles off New Zealand's coast. Authorities have confirmed that five people died. They expect that number to rise as some are missing and police officials issued a statement that flights around the islands revealed "no signs of life had been seen at any point,", as The Guardian reported.

"Based on the information we have, we do not believe there are any survivors on the island," the police said in their official statement. "Police is working urgently to confirm the exact number of those who have died, further to the five confirmed deceased already."

The eruption happened on New Zealand's Whakaari/White Island, an islet jutting out of the Bay of Plenty, off the country's North Island. The island is privately owned and is typically visited for day-trips by thousands of tourists every year, according to The New York Times.

At the time of the eruption on Monday, about 50 passengers from the Ovation of Seas were on the island, including more than 30 who were part of a Royal Caribbean cruise trip, according to CNN. Twenty-three people, including the five dead, were evacuated from the island.

The eruption occurred at 2:11 pm local time on Monday, as footage from a crater camera owned and operated by GeoNet, New Zealand's geological hazards agency, shows. The camera also shows dozens of people walking near the rim as white smoke billows just before the eruption, according to Reuters.

Police were unable to reach the island because searing white ash posed imminent danger to rescue workers, said John Tims, New Zealand's deputy police commissioner, as he stood next to Prime Minister Jacinda Ardern in a press conference, as The New York Times reported. Tims said rescue workers would assess the safety of approaching the island on Tuesday morning. "We know the urgency to go back to the island," he told reporters.

"The physical environment is unsafe for us to return to the island," Tims added, as CNN reported. "It's important that we consider the health and safety of rescuers, so we're taking advice from experts going forward."

Authorities have had no communication with anyone on the island. They are frantically working to identify how many people remain and who they are, according to CNN.

Geologists said the eruption is not unexpected and some questioned why the island is open to tourism.

"The volcano has been restless for a few weeks, resulting in the raising of the alert level, so that this eruption is not really a surprise," said Bill McGuire, emeritus professor of geophysical and climate hazards at University College London, as The Guardian reported.

"White Island has been a disaster waiting to happen for many years," said Raymond Cas, emeritus professor at Monash University's school of earth, atmosphere and environment, as The Guardian reported. "Having visited it twice, I have always felt that it was too dangerous to allow the daily tour groups that visit the uninhabited island volcano by boat and helicopter."

The prime minister arrived Monday night in Whakatane, the town closest to the eruption, where day boats visiting the island are docked. Whakatane has a large Maori population.

Ardern met with local council leaders on Monday. She is scheduled to meet with search and rescue teams and will speak to the media at 7 a.m. local time (1 p.m. EST), after drones survey the island, as CNN reported.
