Defense Secretary James Mattis remarked recently that a war with North Korea would be “tragic on an unbelievable scale.” No kidding. “Tragic” doesn’t even begin to describe the horrors that would flow from such a conflict.

The Korean peninsula, all 85,270 square miles of it, is about the size of Idaho. It contains more soldiers (2.8 million, not counting reserves) and armaments (nearly 6,000 tanks, 31,000 artillery pieces, and 1,134 combat aircraft) than any other place on the planet. The armies of North and South Korea face each other across the Demilitarized Zone, or DMZ, and Seoul, South Korea’s capital, is a mere 35 miles away as the artillery shell flies. More than 25 million people inhabit that city’s greater metropolitan area, home to about half of South Korea’s population. Unsurprisingly, untold numbers of North Korean missiles and artillery pieces are trained on that city. Once the guns started firing, thousands of its denizens would undoubtedly die within hours. Of course, North Koreans, too, would be caught in an almost instant maelstrom of death.

And the war wouldn’t be a bilateral affair. South Korea hosts 28,500 American troops. In addition, there are some 200,000 American civilians in the country, most of them in Seoul. Many in both categories could be killed by North Korean attacks and the United States would, in turn, hit multiple targets in that country. Pyongyang might retaliate by firing missiles at Japan, where 39,000 American troops are stationed, concentrating on the network of American bases and command centers there, especially the US Services Headquarters at Yokota Air Base near Tokyo.

And that’s without even considering the possible use of nuclear weapons. If anything, Mattis’s description is an understatement. And don’t assume that the danger of a Korean conflagration has passed now that President Trump has become trapped in the latest set of political scandals to plague his administration. Quite the opposite: A clash between North Korea and the United States might have become more probable precisely because the president is politically besieged.

Trump wouldn’t be the first leader, confronted with trouble at home, to trigger a crisis abroad and then appeal for unity and paint critics as unpatriotic. Keep in mind, after all, that this is the man who has already warned of “a major, major war” with North Korea.

Trump vs. Kim

So far the coercive tactics Trump has used to compel North Korea to dismantle its nuclear weapons program and cease testing ballistic missiles have included sanctions and asset freezes, military threats, and shows of force—both serious, as in the recent Key Resolve and Operation Max Thunder joint military exercises with South Korea, and farcical, as with a supposedly northward-bound naval “armada” that actually sailed in the opposite direction.

Such moves all involve the same presidential bet: that economic and military pressure can bend Pyongyang to his will. Other American presidents have, of course, taken the same approach and failed for decades now, which seems to matter little to Trump, even though he presents himself as a break-the-mold maverick ready to negotiate unprecedented deals with foreign leaders.

By now, this much ought to be clear, even to Trump: North Korea hasn’t been cowed into compliance by Washington’s warnings and military muscle flexing. In 2003, after multilateral diplomatic efforts to denuclearize North Korea ran aground, Pyongyang ditched the Nuclear Non-Proliferation Treaty (NPT) and two years later declared that it possessed nuclear weapons. In October 2006, it detonated its first nuclear device, a one-kiloton bomb. Four other tests in May 2009, February 2013, January 2016, and September 2016, ranging in explosive yield from four to 10 kilotons, followed. Three of them occurred after the current North Korean leader, Kim Jong-un, came to power in April 2012.

A similar pattern holds for ballistic missiles, which North Korea has been testing since 1993. The numbers have risen steadily under Kim Jong-un, from four tests in 2012 to 25 in 2016.

Clearly, the North’s leaders reject the proposition that American approval is required for them to build nuclear bombs and ballistic missiles. Like his father, Kim Jong-il, and his grandfather, Kim Il-sung, the founder of the Democratic People’s Republic of Korea (or DPRK, North Korea’s official name), Kim Jong-un is an ardent nationalist who regularly responds to threats by upping the ante. Trump’s national security adviser, General H.R. McMaster, characterized Kim as “unpredictable.” In reality, the Korean leader, like his father and grandfather before him, has been remarkably consistent: He has steadfastly refused to stop testing either nuclear weapons or their possible delivery systems, let alone “denuclearize” the Korean peninsula, as McMaster demanded.

Indeed, from Pyongyang’s perspective Trump may be the unpredictable one. On one day, amid press reports that the Pentagon was considering a preventive strike using means ranging from Tomahawk cruise missiles to cyber attacks, the president declared ominously that North Korea “is a problem, a problem that will be taken care of.” He followed up by warning Chinese President Xi Jinping, whom he was then hosting at his Mar-a-Lago estate, that if China wouldn’t rein in Kim, the United States would act alone. Not so long after, Trump suddenly praised Kim, calling him a “pretty smart cookie,” presumably impressed that the North Korean leader wasn’t even 30 years old when he succeeded his father. On yet another day, the president announced that he would be “honored” to meet Kim under the right circumstances and would do so “absolutely.”

The roller-coaster ride otherwise known as the presidency of Donald Trump has many people perplexed. Trump’s boosters believe that the president’s unpredictability gives him leverage against adversaries. But in the event of a military crisis on the Korean peninsula, Trump’s pendulum-like behavior could lead North Korea’s leaders to conclude that they had best prepare for the worst—and so strike first. That prospect makes the Kim-Trump combination not just dangerous but quite possibly deadly.

Old Claims, New Possibilities

Standing in the way of a fresh policy toward North Korea are a set of assumptions beloved within the Washington Beltway and by the foreign policy establishment beyond it—and rarely challenged in the mainstream media.

Perhaps the most common of them is that diplomacy and conciliation toward North Korea won’t work because its leaders only respond to pressure. So pervasive and deeply rooted is this view that it makes fresh thinking about Pyongyang next to impossible.

Given the failure of both sanctions and saber rattling, however, a new approach would have to involve diplomacy (in case you’ve forgotten that word) and serious negotiations with the North. Here’s one possible way to go that might, in fact, make a difference.

North Korea would agree, in principle, to dismantle its nuclear weapons installations, rejoin the NPT, and allow comprehensive inspections by the International Atomic Energy Agency (IAEA) to verify its compliance. Concurrently, the United States would pledge not to attack North Korea or topple its regime and to move toward normalization of political relations.

Major steps taken by North Korea on the path to denuclearization would be matched by cuts in American military forces in South Korea. Once Pyongyang delivered completely, the United States would remove all its forces and fully lift economic sanctions on the North.

The United States, South Korea, China, Japan, and Russia would undertake to fund and, for some of its future energy needs, build new Light-Water Reactors (LWRs), which reduce the risk of bomb-grade plutonium production. These would be subject to regular inspections and electronic surveillance by the IAEA and all spent fuel would be transported out of North Korea. The dismantling of the North’s nuclear facilities, verified by intermittent inspections and continuous electronic monitoring, would—as in the nuclear deal with Iran—prevent the production of weapons-grade plutonium (PU-239) or uranium (UR-235)

Once these steps were completed, both Koreas would begin to pull back their troops massed along the Demilitarized Zone and so create an even wider region free of weapons and troops between the two countries. They would agree not to reintroduce troops and armaments into the vacated areas and to allow monitoring by international observers. Over perhaps a 10-year span the two states would commit to additional military pullbacks plus reductions in the number of weapons each possessed, focusing on retiring those most suited to offensive warfare.

If Trump is indeed prepared to meet with Kim, it should be to do a deal along these lines, not to deliver in person the sort of ultimatums that the North has rejected for years.

The Diplomacy-Won’t-Work Trope

Typically, proposals like these are dismissed on the grounds that they combine the worst of all worlds: the appeasement of a despotic regime and reckless naïveté.

Let’s start with the appeasement charge, the gist of which seems to be that Pyongyang’s cruelties bar diplomatic engagement with it. This claim amounts to sanctimonious puffery and historical amnesia. The United States has, in various forms, supported a vast array of despotic regimes, including Greece during the brutal “regime of the colonels” (1967-74); Indonesia under Suharto (who presided over the slaughter of half a million people in 1965-1966); and Iraq under Saddam Hussein during the 1980s, when his government was gassing Kurds and razing their villages. And of course in South Korea there was the US-backed government of President Syngman Rhee (1948-1960), whose security forces killed more than 100,000 people, 30,000 to 60,000 in the infamous 1948 Cheju massacre alone, as part of an effort to decimate any left-wing opposition in the country.

Counting on China, Pyongyang’s principal benefactor, or Russia to squeeze North Korea so that it undertakes far-reaching reforms amounts to wishful thinking. Neither country wants to trigger instability there for fear that the country might collapse, creating mayhem on its borders and releasing a floodtide of refugees that they would have to deal with. In addition, China views the North as a buffer with South Korea, an American ally and a forward base for US military power. From Beijing’s vantage point, if changes in North Korea careened out of control, the eventual result could be a unified Korean state allied with Washington. For the Chinese, the status quo on the peninsula, while anything but ideal, beats such a roll of the dice. Beijing has been willing to impose sanctions on Pyongyang and sees it as mercurial and reckless, but it is not about to strangle it economically.

As for the charge of naïveté when it comes to a proposal to begin the partial demilitarization of the peninsula, that’s part and parcel of prevailing Washington orthodoxy, a deep conviction that North Korea will never surrender its nuclear weapons as part of a grand bargain. In fact, progress toward just such a denuclearization was made during Bill Clinton’s presidency, when the sticks were briefly put aside and the carrots brought out. In October 1994, negotiations led to what was called the Agreed Framework.

Its details are complicated, so brace yourself for a barebones summary: North Korea agreed to shut down its reactor at Yongbyon, place the plant’s spent fuel in sealed containers for shipment out of the country, stop construction on two larger reactors (at Yongbyon and Taechon), remain a party to the NPT, and permit the IAEA to inspect its nuclear sites to verify the agreement’s implementation. In exchange, the United States, Japan, and South Korea undertook, through a consortium, to build two light-water reactors (LWRs) suitable for generating electricity but not for producing weapons-grade plutonium and to provide Pyongyang with 500,000 metric tons of heavy fuel oil pending the completion of the reactors.

Eventually the Agreed Framework fell apart, a development for which all the parties share blame. North Korea’s ongoing missile tests, while not banned by the deal, bolstered the accord’s critics in Washington. It also faced resistance in both the Senate and the House of Representatives, which in 1994 were, for the first time in four decades, in Republican hands, while the Clinton administration proved inept in defending the agreement. Having stopped producing plutonium at Yongbyon, North Korea complained about the delay in building the LWRs. (Work on the first reactor didn’t start until August 2002.) The South Korean government, stuck with partially funding those plants, was unenthusiastic, too.

The Bush administration arrived in office in 2001 ready to shred the Agreed Framework. Soon enough, however, it sought to resurrect a version of that deal during the “Six-Party Talks,” which began in 2003 and included both Koreas, the United States, Russia, China, and Japan.

Here again the details are labyrinthine, but the basic formula that emerged did indeed resemble the Agreed Framework: North Korea was to receive both those LWRs and economic aid in exchange for freezing and then dismantling its nuclear program. The North Koreans even allowed American and other technical experts to observe it shutting down the Yongbyon reactor. It also provided reams—18,000 pages to be exact—of documentation on its nuclear program. Most importantly, having frozen plutonium production in 1994, it continued to do so until 2003.

For its part, the Bush administration removed North Korea from the State Department’s list of countries accused of sponsoring terrorism and exempted it from the Trading with the Enemy Act.

There were also threats, theatrics, and setbacks aplenty. In the end, the Six-Party Talks failed for reasons similar to those that killed the Agreed Framework: quarrels over the nature and scope of verification procedures, North Korea’s missile tests and confirmation of reports that it had embarked on efforts to build uranium-based nuclear weapons, and UN sanctions. President George W. Bush, of course, included that country, along with Iran and Iraq, in what he infamously termed the “axis of evil,” which he called a “grave and growing danger” in his January 2002 State of the Union address. His administration also listed North Korea in the 2002 Nuclear Posture Review as one of the states that might become the target of a preventive strike.

The lessons to be drawn from this grim record are not that North Korea will not negotiate, let alone that it won’t ever agree to freeze, or even terminate, its nuclear program. Instead, the history of these failed deals should be looked to for ideas on better ways to reach a consensus-based solution.

This much remains clear: The more Pyongyang suspects that Washington’s real goal is regime change, the less likely it will be to relinquish its nuclear weapons for fear of suffering the fate of Moammar Gadhafi, who shut down his nuclear program only to be toppled in what began as a US and NATO humanitarian intervention to protect civilians but morphed quickly into a campaign to take him out.

North Korea and the Legacy of War

The notion that North Korea couldn’t possibly fear an American attack and that its claims to the contrary amount to paranoia reflects a stunning ignorance of history. Between 1950 and 1953, North Korea experienced firsthand the devastation the American military machine was capable of inflicting. As Charles Armstrong, a historian of Korea, has written, in those years “American planes dropped 635,000 tons of bombs on Korea—that is, essentially North Korea—including 32,557 tons of napalm, compared to 503,000 tons of bombs dropped in the entire Pacific theater of World War II.” Armstrong estimates that 12 percent–15 percent of the North Korean population might have died, “a figure close to or surpassing the proportion of Soviet citizens killed in World War II.”

As happened during the Anglo-American terror bombing of Germany and Japan, the distinction between civilians and soldiers, so central to International Humanitarian Law and Just War Theory, was defenestrated. Many Americans know about the bombing of Dresden, Berlin, Hamburg, Hiroshima, and Nagasaki and the deliberate targeting of civilians in an attempt to break their morale. But few know what happened to North Korea in the early 1950s. In his haunting book, On the Natural History of Destruction, W.G. Sebald writes that Germans did not discuss the wartime bombings because Nazi crimes made them hesitant to cast moral judgments on other states, no matter what they had done to Germany. There has been no such repression of memory or reticence by the state or the citizenry of North Korea.

As a result, the usual dismissals of Pyongyang’s apprehension about what the United States might do to a denuclearized country are both callous and foolish. Successful negotiations would mean taking its security concerns seriously, not rejecting them as paranoid demands, especially given that American military power remains so close, that Washington has threatened to attack the North more than once, and that the American president only recently boasted to the president of the Philippines (in a conversation leaked online) of the two US nuclear submarines that were evidently somewhere off the North Korean coast at that moment.

Cutting the Umbilical Cord

A grand bargain that combines aid and political normalization in return for denuclearization and the pullback and reduction of troops on the Korean peninsula could be made even more attractive to Pyongyang if it included a phased withdrawal of the 28,500 American troops in South Korea. The standard claim—that this would leave South Korea defenseless—is ludicrous.

South Korea has twice the population of the North: 50.6 million to 25.2 million, and they are better educated, far better fed, and much healthier. Just look at the data on life expectancy, infant mortality, and the amount and quality of calories consumed. The South, then, has far more and better human capital. Ready to Fight Back?

The gap in economic power is gargantuan. South Korea, an industrial and technological powerhouse, has a $1.5 trillion gross domestic product (GDP), the world’s 12th largest. Valued at $30 billion, North Korea’s ranks 115th internationally, barely ahead of Senegal’s. In other words, South Korea’s economy is about 50 times larger than the North’s, and its per capita GDP ($37,900) exceeds North Korea’s ($1,800—and so comparable to South Sudan’s) by a factor of 21. It doesn’t matter whether you’re talking about investments in education and technology or living standards, South Korea inhabits a different universe than the North.

Confronted with such economic comparisons your garden variety Washington military wonk might quip, “Fine, but GDP doesn’t fight.” Fair enough, strictly speaking. So let’s ignore the multiple ways in which wealth shapes military power and consider the military data alone. The results may surprise you.

According to the most recent State Department estimate, South Korea spends more than seven times what North Korea does on its armed forces. And given the South’s technological prowess and purchases of American arms, it has a far more modern military than the North, which still uses Soviet and Chinese armor and aircraft developed during the 1950s and 1960s. Then there’s the relative burden of military spending. South Korea allocates 2.6 percent of its GDP to its armed forces, North Korea, 23.3 percent. In other words, South Korea can easily increase military spending without undue hardship. Not so North Korea.

Remember this the next time you hear that the North has many more troops, tanks, artillery, and submarines. Remember as well that the numerical balance is about even or substantially favors the South in other armaments, such as combat aircraft, frigates, and destroyers.

In other words, in a future settlement that includes a stage-by-stage US military withdrawal, South Korea will hardly be left defenseless.

Averting Apocalypse?

Since the end of the Korean War, crises on the peninsula have come and gone. Some have been dangerous indeed. In the run-up to the 1994 Agreed Framework, for example, Defense Secretary William Perry proposed military options that included increasing the number of American troops in South Korea and readying long-range bombers and aircraft carrier battle groups to strike the Yongbyon reactor.

Still, the current crisis has no equal. Sitting in the White House is a president whose narcissism knows no bounds, whose ignorance of the world is staggering, who talks blithely about war and nuclear weapons, and who is besieged by political scandals. Meanwhile, North Korea’s ruler, like his predecessors, refuses to be cowed by American shows of force and continues to test ballistic missiles—three in May alone.

A deal resembling the one sketched above may never be reached and, given past history, it won’t be arrived at easily. Yet threats and displays of military power by the United States haven’t worked. Ever. If President Trump acts on the assumption that he and “his” generals can make them work and that North Korea will become reasonable only when faced with the certainty of war, there could be a conflagration on the Korean peninsula the likes of which would be almost unimaginable.
