The release last week of the Obama administration's Nuclear Posture Review brings long overdue attention to the vital issue of U.S. strategic posture. Issues raised in the NPR and START have reinvigorated a crucial national nuclear dialogue that has been missing.

As the chairman and vice chairman of Congress's bipartisan Strategic Posture Commission, which issued its report last May, we have watched with great interest the administration's steady progress this past year on its Nuclear Posture Review and the START negotiations.

Themes from our report run through the Nuclear Posture Review and are embodied in the new START agreement. While debate and disagreement must be part of the crossfire in this renewed nuclear dialogue, we want to emphasize important dimensions of both the Posture Review and START treaty that figure prominently in our bipartisan report.

Now that the NPR is completed, we see that it is compatible with our recommendations. The review gives a comprehensive and pragmatic plan for reducing nuclear risks to the United States. We believe it offers a bipartisan path forward - while allowing for healthy disagreements on specific issues.

And it incorporates many of our points - such as pursuing a quick and modest reduction of nuclear weapons with Russia and sustaining the nuclear triad of land-based ICBMs, sea-based SLBMs and bombers. It also recognizes that nuclear weapons safeguarded U.S. security during the Cold War by deterring attack and that we will need them for deterrence in the foreseeable future, as long as others also possess them.

We also see that the NPR puts special emphasis, as our report recommended, on improving the nation's complex nuclear infrastructure and enhancing programs to recruit and keep the nation's best scientific minds. The administration's commitment to increase investment in our national laboratories also ensures that they continue their important role in sustaining a safe, secure and effective nuclear arsenal and in solving many other problems facing the nation.

The review is correct to make preventing nuclear terrorism and proliferation the top priority, while also seeking to strengthen deterrence and to reassure U.S. allies and recognizing the importance of strategic stability with Russia and an emerging China. Our commission reached the same conclusions.

The NPR's changes in U.S. declaratory policy - especially the assurance that Washington "will not use or threaten to use nuclear weapons against non-nuclear parties to the Nonproliferation Treaty that are in compliance with their nuclear nonproliferation obligations" - go beyond our recommendation that the U.S. retain "calculated ambiguity."

It is, however, a sensible variation on a theme that the U.S. should support nonproliferation while preserving deterrence for itself and its allies.

We also note that the NPR chose, as we advised, to avoid adopting a "no first use" policy for nuclear weapons while narrowing the scope of possible first use to "extreme circumstances" - language that was in our bipartisan report.

We believe that the substantial edge the U.S. has developed in conventional military capabilities, which the NPR notes, permits this country to sharply reduce reliance on nuclear weapons. But we caution those who make light of this major U.S. strategic advantage and its implications.

We support the NPR's call for the U.S. not to develop new nuclear weapons now. Our report similarly called for a case-by-case approach to extending the life of today's warheads. And we agree that the focus should be on safety, security and reliability - not developing new military capabilities.

The NPR echoes our call to negotiate a worldwide end to the production of new fissile materials - the key ingredients of nuclear weapons.

Our final report strongly endorsed the U.S. deterrence policy to cover our allies and partners with the U.S. nuclear umbrella - an objective the NPR also embraces.

The report suggested deploying proven missile defenses against threats such as North Korea and Iran but emphasized, as the NPR does, that these defenses should not be so big as to encourage Russia to add warheads to counter them, which would only undermine efforts to reduce nuclear weapons. We included China as well as Russia in this.

But in two areas, we believe the NPR might have fallen short of the mark.

First, we understand that the review considered declassifying additional information about the size and composition of the U.S. nuclear stockpile. It should have done so. This would demonstrate U.S. leadership on the transparency that is needed to secure nuclear materials globally and to bolster strategic stability with Russia and China.

Second, the NPR called for the consideration of conventional "prompt global strike" capabilities. But it did not explain whether these systems would have a niche role against small regional powers such as North Korea or be an ultimate substitute for nuclear weapons in deterrence with Russia and China.

We feel the former is the only sensible approach. Keeping this issue ill-defined creates needless anxiety in Moscow and Beijing that could lead to future problems.

Even with these two caveats, the 2010 Nuclear Posture Review makes important strides in charting a sustainable bipartisan path forward for the United States.

Healthy disagreement over some NPR specifics should not obscure the valuable contribution it makes to advancing U.S. security interests - resting, as it does in part, on our bipartisan 2009 Strategic Posture Commission report.

William J. Perry served as secretary of defense in the Clinton administration. He was chairman of the Congressional Commission on the Strategic Posture of the United States. James R. Schlesinger was the nation's first energy secretary and served as secretary of defense from July 1973 to November 1975. He was vice chairman of the Congressional Commission on the Strategic Posture of the United States.

THIS has been a remarkable time for the Obama administration. After a year of intense internal debate, it issued a new nuclear strategy. And after a year of intense negotiations with the Russians, President Obama signed the New Start treaty with President Dmitri Medvedev in Prague. On Monday, the president will host the leaders of more than 40 nations in a nuclear security summit meeting whose goal is to find ways of gaining control of the loose fissile material around the globe.

New Start is the first tangible product of the administration's promise to "press the reset button" on United States-Russian relations. The new treaty is welcome. But as a disarmament measure, it is a modest step, entailing a reduction of only 30 percent from the former limit - and some of that reduction is accomplished by the way the warheads are counted, not by their destruction. Perhaps the treaty's greatest accomplishment is that the negotiations leading up to its signing re-engaged Americans and Russians in a serious discussion of how to reduce nuclear dangers.

So what should come next? We look forward to a follow-on treaty that builds on the success of the previous Start treaties and leads to significantly greater arms reductions - including reductions in tactical nuclear weapons and reductions that require weapons be dismantled and not simply put in reserve.

But our discussions with Russian colleagues, including senior government officials, suggest that such a next step would be very difficult for them. Part of the reason for their reluctance to accept further reductions is that Russia considers itself to be encircled by hostile forces in Europe and in Asia. Another part results from the significant asymmetry between United States and Russian conventional military forces. For these reasons, we believe that the next round of negotiations with Russia should not focus solely on nuclear disarmament issues. These talks should encompass missile defense, Russia's relations with NATO, the Conventional Armed Forces in Europe Treaty, the Intermediate-Range Nuclear Forces Treaty, North Korea, Iran and Asian security issues.

Let's begin with missile defense. Future arms talks should make a serious exploration of a joint United States-Russia program that would provide a bulwark against Iranian missiles. We should also consider situating parts of the joint system in Russia, which in many ways offers an ideal strategic location for these defenses. Such an effort would not only improve our security, it would also further cooperation in dealing with the Iranian nuclear threat, including the imposition of consequential sanctions when appropriate.

NATO is a similarly complicated issue. After the cold war ended, Russia was invited to NATO meetings with the idea that the country would eventually become an integral part of European security discussions. The idea was good, but the execution failed. NATO has acted as if Russia's role is that of an observer with no say in decisions; Russia has acted as if it should have veto power.

Neither outlook is viable. But if NATO moves from consensus decisions to super-majority decisions in its governing structure, as has been considered, it would be possible to include Russia's vote as an effective way of resolving European security issues of common interest.

The Russians are also eager to revisit the two landmark cold war treaties. The Conventional Armed Forces in Europe Treaty enabled NATO and Warsaw Pact nations to make significant reductions in conventional armaments and to limit conventional deployments. Today, there is still a need for limiting conventional arms, but the features of that treaty pertaining to the old Warsaw Pact are clearly outdated. Making those provisions relevant to today's world should be a goal of new talks

Similarly, the 1987 treaty that eliminated American and Soviet intermediate-range ballistic missiles was a crucially important pact that helped to defuse cold war tensions. But today Russia has neighbors that have such missiles directed at its borders; for understandable reasons, it wants to renegotiate aspects of this treaty.

Future arms reductions with Russia are eminently possible. But they are unlikely to be achieved unless the United States is willing to address points of Russian concern. Given all that is at stake, we believe comprehensive discussions are a necessity as we work our way toward ever more significant nuclear disarmament.

North Korea is usually described as the “most isolated country on earth,” its people effectively cut off from the outside world. My research tells a different story—that perhaps one million North Koreans are secretly listening to foreign radio broadcasts. The number of listeners is believed to be growing, which is all the more amazing when one considers that North Korean authorities only distribute radios with fixed dials, assiduously jam foreign broadcasts, and send citizens caught listening to foreign radio to the country’s notorious gulags for as long as ten years.

Over a dozen radio stations from the United States, South Korea, and Japan currently broadcast to North Korea. Voice of America (VOA), one of the most popular stations, has been broadcasting to the North since 1942, while the equally popular Radio Free Asia (RFA) began its Korean broadcasts soon after being created by Congress in 1997. VOA focuses on news of the United States and the world, while RFA concentrates on the two Koreas. RFA also carries commentaries by two Korean speakers who grew up in the former Soviet Union and Romania. RFA serves as a substitute for the lack of a “free” station in North Korea, but unlike a typical “surrogate station”—which would be staffed largely by émigrés—RFA only employs one North Korean defector.

South Korea’s “Global Korean Network” has been declining in popularity since it ceased to focus on North Korea and adopted a decidedly soft approach after the election of Kim Dae-jung as president in 1997. However, three stations run by North Korean defectors have sprouted up over the past few years, led by Free North Korea Radio (FRNK). These stations employ stringers in North Korea who can communicate by cell phone or smuggle out interviews through China. As a result, information is flowing in and out of the North more rapidly than ever. For example, when major economic reforms were undertaken in 2002, it was months before the rest of the world knew. In contrast, when the regime launched a disastrous currency reform on November 30, 2009, FNKR filed a report within hours.

How do we know that North Koreans are actually listening to foreign broadcasts? First, on dozens of occasions, authorities in Pyongyang have used their own media to attack foreign broadcasters. The North reserves the insult “reptile” exclusively to describe foreign broadcasters. In late March 2010, the regime likened defector broadcasters to “human trash.” Ironically, this diatribe also contained the first official mention of the currency revaluation, so broadcasters have clearly struck a nerve. If they were in fact irrelevant, the regime would ignore them instead of lavishing them with free publicity.

Broadcasters to North Korea frequently receive heartbreaking messages from North Koreans in China, thanking them for their efforts. One listener described RFA as “our one ray of hope.” More importantly, over the past several years, thousands of North Korean defectors, refugees, and visitors to China have been interviewed about their listening habits. An unpublished 2009 survey of North Koreans in China found that over 20 percent had listened to the banned broadcasts, and almost all of them had shared the information with family members and friends. Several other surveys confirm these findings. While we cannot generalize the listening habits of a self-selected group to the general population, it is not unreasonable to conclude that there are more than a million surreptitious listeners. The North Korean regime is not only losing its monopoly on the control of information; defectors also cite foreign radio listening as one of the leading motivations to defect.

Despite valiant efforts and growing impact, much more could be done to improve broadcasting to North Korea. VOA and RFA only broadcast five hours a day, and the defector stations limp along with shoestring budgets, due to a pervasive indifference within South Korea.

President Obama’s human rights envoy for North Korea, Robert King, has pledged to expand funding for Korean broadcasting. For its part, Pyongyang claims that foreign broadcasts are part of the Obama administration’s “hostile policy” toward the North. Only time will tell if these efforts will lead to change we can believe in—both in Washington and Pyongyang.
