North Korea's renewed bid for nuclear weapons poses an urgent, serious foreign policy challenge to the United States. The current situation -- though it bears a resemblance to the events of 1993-1994 -- is far more dangerous and difficult. North Korea has developed longer-range ballistic missiles; South Korea's growing nationalism has put its U.S. relations on shakier ground; and the United States is distracted by the wars on terrorism and for regime change in Iraq.

Despite these challenges, good prospects still exist for a diplomatic resolution to the North Korea problem. North Korea's dire economic circumstances have made it more vulnerable to outside pressure at a time when its neighbor nations and the United States are increasingly concerned about its nuclear ambition. Military means would not only exact huge human casualties but also deepen U.S. estrangement from Seoul and diminish prospects for developing a joint strategy with other Asian powers.

Given the urgency and complexity of the current situation, appointment of a special coordinator for North Korean policy could help the administration to formulate a unified policy, sell it to Congress, coordinate it with allies, and present it to Pyongyang. In any event, a key requirement will be real "give and take" negotiations with South Korea to arrive at a coordinated strategy.

In the end, Pyongyang must choose: economic assistance and security assurance on the condition that all nuclear activities be abandoned, or dire consequences if nuclear programs continue. Any new agreement, however, must avoid the deficiencies of the 1994 Agreed Framework. It must be more verifiable, less readily reversible, more comprehensive, more politically defensible, and more enforceable through the involvement of North Korea's neighbors.

What is the impact of the events of September 11 and the subsequent "war on terrorism" on nuclear issues? The "war on terrorism" is a handy political moniker for what the United States must learn to do in response to changes that have actually been taking place over several years. Some of the US responses to date have been wise. Some need a new look. Perhaps most important, in some areas, the United States and other countries have not responded and may be at a loss to respond, given the constraints on their policies. Some of these lacking responses provide the most important items on the post September 11 security agenda. In what follows, I will give one view of what these are and what to do about them.

I begin with nuclear terrorism, particularly the possibility of using nuclear weapons for terrorist purposes. The next section addresses the related issue of nuclear proliferation to state and non-state actors. The events of September 11 have given a new twist to that issue. There is a relationship between the possibility of nuclear weapons getting into terrorists' hands and the problems in Iraq, South and Central Asia, and North Korea. The following sections deals with an item that is no longer high on the US political agenda but which is tied to proliferation and terrorism and has a greater long-range potential for causing trouble, the incipient nuclear rivalries around the world. In closing, I suggest some elements of a desirable nuclear posture to deal with some of the problems outlined.

Protesters who marched around the world last week were wrong to assume that American inaction against Iraq will make their children safer or the Iraqi people better off. (Wouldn't it be nice if the Iraqi people could express their opinion about their country's future rather than having to listen to George W. Bush, Saddam Hussein or street protesters speak on their behalf?) The protesters were right, however, to question whether war against Iraq will produce more security at home and real freedom for the Iraqi people.

Americans should have confidence that the Department of Defense has a game plan and the capacity to destroy Hussein's regime, but we have less reason to feel the same level of confidence about the blueprint and resources earmarked to rebuild Iraq because no one talks about them.

The time for circulating such plans and amassing such resources is now, before the bombs begin to fall. A war to disarm Hussein alone is not legitimate. Only a military conflict that brings about genuine political change in Iraq will leave the Iraqi people better off and the American people more secure. Winning the war will be inconsequential if we fail to win the peace.

To demonstrate a credible commitment fto rebuild a democratic Iraqi over the long haul, the Bush administration could do the following today:

First, if we must go to war, we cannot go alone. American armed forces can destroy Hussein's regime without France or Germany, but the U.S. Agency for International Development will struggle to rebuild a new Iraqi regime without the assistance of others.

Second, President Bush must state clearly before the conflict begins that an international coalition will govern Iraq for an interim term. Again, the burden will fall mainly on American armed forces and their commanders. But the less the occupation looks like an American unilateral action, the better.

Third, the Bush administration must secure a commitment from all stakeholders in a post-war Iraqi regime about the basic contours of a new constitution for governing Iraq before war begins. Right now, these claimants on a future Iraqi regime are weak. They need the United States to come to power, which gives American officials considerable leverage now. Once Hussein's regime falls, however, they will be less beholden to the Americans. Without a clearly articulated plan in place before the fall of Hussein's regime, the process of constituting a new government could quickly become chaotic and unpredictable.

Fourth, President Bush must make absolutely clear now -- before war -- that the United States has no intention of seizing Iraqi oil fields, which belong to the Iraqi people. Bush must distance himself from statements made by unnamed government officials that the United States plans to appropriate Iraqi oil revenues as reparations.

This absurd idea -- believed by many throughout the world -- must be squelched immediately and unequivocally. Instead, the Bush administration should consider privatizing the Iraqi oil business through a mass voucher program. Give every Iraqi citizen a small stake in the ownership of these resources. At a minimum, an international consortium, not an American general, must assume stewardship of the Iraqi oil business during occupation.

On Day One after Hussein is defeated, Bush must demonstrate a real commitment to the promotion of democracy in the region. Most importantly, the rebuilding of Iraq must begin immediately. The delays we are witnessing in Afghanistan cannot be repeated.

In this cause, the American people should also help through the direct delivery of aid, student exchanges, or sister-city programs. Those who rallied in support of peace last week should remain mobilized to promote peace and development in Iraq after a military conflict, when the Iraqi people will be in greatest need.

In parallel, Bush must demonstrate a more serious commitment to rebuilding a state in Afghanistan -- hopefully as a democracy, but at least as a functioning, coherent state that can maintain order and promote development. This can happen only if the warlords are contained, an assignment that will require several times the several thousand peacekeeping troops now in the country. Western aid workers in Afghanistan -- including those working on democracy -- complain that internal security is a precondition for any aid to be effective.

In addition, Bush must formulate a policy toward Iran, which could begin by stating clearly that the United States does not intend to use force against that country. The current ambiguity about American intentions only strengthens the hard-liners within Iran and weakens the reformers. More fundamentally, the United States must develop a more sophisticated policy toward Iran, one which engages reformers within the Iranian government and assists democratic forces in society, but does not legitimate hard-line clerics who control the regime. The model is American policy toward the Soviet Union in its waning years.

And President Bush should redouble his administration's efforts to help create a democratic Palestine. A democratic Palestine is not a reward to the Sept. 11 terrorists, but their worst nightmare. Of course, this undertaking is enormous, but no larger than the task of installing democracy in Iraq after invasion.

Bush should also call his counterparts in Saudi Arabia, Pakistan and Egypt and tell them privately the truth -- regime change in their countries has already begun. If they initiate political liberalization now while they are still powerful and their enemies are still weak, they might be able to shape the transition process according to their interests as the king did in Spain and Augusto Pinochet did in Chile. If the Saudis, Pakistanis and Egyptians wait, however, their regimes are more likely to end in revolution like Iran in 1979 or Romania in 1989.

Even if President Bush undertakes all these initiatives, an invasion of Iraq is still likely to produce a net loss of political liberalization in the region in the short run. Dictatorships in the region are not going to suddenly liberalize in response to the American occupation of Iraq. In the face of angry publics, they will do the exact opposite -- just as autocrats across Europe did two centuries ago when Napoleon tried to bring democracy to the continent through the barrel of a gun.

American leaders, therefore, will face greater and more complex challenges after the war than before the war. To succeed, Bush and his successors need a long-term game plan. Above all, the president must explain to the American people that the United States will be involved in the reconstruction of a democratic Iraq and the region for decades, not months or years.

The worst-case scenario -- for both Americans and Iraqis -- is a quick war, followed by a terrorist attack on American troops stationed in Iraq, followed by a call for early American disengagement. Twenty years ago, the United States helped to destroy the Soviet-sponsored regime in Afghanistan, but then failed to help build a new regime in the vacuum. We experienced the consequences of such shortsightedness on Sept. 11, 2001. In Iraq or elsewhere in the region, we cannot make the same mistake again.

STANFORD -- In May 1988, President Reagan traveled to Moscow for a summit with Soviet leader Mikhail S. Gorbachev. When he became president, Reagan had called the Soviet Union the "evil empire," but at the time of his historic trip its leader was a personal friend. Reagan didn't allow his friendship with Gorbachev to overshadow his human rights agenda. Speaking in Helsinki two days before entering the Soviet Union, Reagan proclaimed: "There is no true international security without respect for human rights.... The greatest creative and moral force in this new world, the greatest hope for survival and success, for peace and happiness, is human freedom."

In Moscow, Reagan echoed this theme at a luncheon at the American ambassador's residence with nearly 100 Soviet human rights activists. Reagan ordered that the ambassador's finest silverware and linens be used to symbolically underscore his respect for the activists, the same as he would accord to Gorbachev.

Reagan's dual-track diplomacy produced results. A few years later, many of his lunch guests occupied positions of authority in a democratizing Russia, a change that had national security implications. Although Russia still possessed thousands of nuclear weapons, its intention to use them against the United States greatly diminished as democratic and market institutions took hold there.

Like Gorbachev and Reagan in 1988, presidents Vladimir V. Putin and Bush have a budding friendship, one that has fostered U.S.-Russian cooperation on important strategic matters like anti-terrorism. Yet, there's a disturbing difference. Some of the same people who attended Reagan's luncheon are again fighting for basic human rights and democratic practices in Russia -- and Bush seems indifferent to their fate.

Putin's backsliding on democracy can no longer be ignored. The Russian leader has overseen a war in Chechnya marked by summary executions, rape, indiscriminate bombing of villages and the inhumane treatment of prisoners of war.

The two largest national television networks do Putin's bidding, and his government and its surrogates have now wrested control of NTV, Russia's third-largest TV network and the only station truly critical of Putin. Print journalists reporting the "wrong" news about Chechnya have been either intimidated, arrested or pushed into exile. Oleg Panfilov, head of the Center for Journalism in Extreme Situations, says, "The number of criminal cases opened against journalists in three years of Vladimir Putin's rule is more than the number during the entire 10 years of Boris Yeltsin's regime."

There is more unnerving evidence of Putin's slide toward authoritarianism. The State Security Service, whose budget is dramatically rising, increasingly harasses human rights activists, environmental leaders and religious groups. Recently, the Russian government expelled the Organization for Security and Cooperation in Europe from Chechnya, terminated its agreement with the U.S. Peace Corps and refused reentry into Russia to American Irene Stevenson, director of the AFL-CIO's Solidarity Center in Moscow. The government has even interfered in electoral politics, removing opposition candidates from the ballot and preventing incumbents from seeking reelection in various regions of the country.

Putin didn't personally orchestrate all these democratic rollbacks, but he also has done nothing to reverse them. The battle over democracy within Russia will largely be won or lost internally. Fortunately, in poll after poll, Russians continue to value democratic ideals and practices. But the Bush administration cannot continue to sit on the sidelines.

Amazingly, it has proposed drastic cuts in the amount of democratic assistance earmarked for Russia next year on the ground -- ironic in light of recent evidence -- that Russian democracy is firmly enough established.

Bush's stance is perplexing. His new national security doctrine declares the promotion of liberty abroad a U.S. priority. Tell that to Russian human rights activists, who feel alienated by the lack of U.S. encouragement.

But democratic activists in Russia need more than words of support. They also need continued U.S. financial and technical help. At a minimum, budgets for democracy assistance, already minuscule, cannot be reduced further. Cutting assistance now, moreover, would send a terrible message about U.S. staying power, not only to democrats in Russia but to those in Afghanistan, Iraq and Uzbekistan.

Congress also has a role to play. Last year, the House and Senate overwhelmingly approved, and Bush signed into law, the Russian Democracy Act, which establishes a minimum for democratic assistance to Russia. Budget cutters in the administration have found creative ways to meet these minimal thresholds by calling programs like high school exchanges "democracy assistance." This sleight of hand must not become law.

Furthermore, in a major report on U.S.-Russian relations a few years ago, Rep. Christopher Cox (R-Newport Beach) called for increased engagement "of the Russian people, not just the Russian government." Now more than ever, Cox and the other authors of this congressional study need to reaffirm their recommendations.

Bush and his foreign team certainly have their hands full. Yet, they cannot allow past victories to slip away while pursuing new ones. A return of dictatorship in Russia, a country armed with thousands of nuclear weapons, would present a much greater threat than the current set of tyrants now threatening U.S. security. To maintain U.S. credibility on issues of democracy and to encourage those within Russia dedicated to the cause of democracy, the Bush administration has to find a way to work constructively with Putin without ignoring Russian society. A good way to start might be a luncheon at the American ambassador's residence in Moscow.
