The United States and Japan have cooperated to address East Asian security issues for many years, and the relationship continues to evolve. Policymakers in Tokyo have grown more confident and assertive. By refining the concept of "self-defense", they have redefined the uses of military force that are considered legitimate under Japan's officially pacifist constitution. These are useful changes, but they have not fundamentally altered the character of the relationship as one between a dominant security patron, the United States, and a vulnerable client, Japan. Washington and Tokyo must work harder to establish Japan as a nation responsible for its own security and capable of assuming a wider strategic role in East Asia.
Outgoing Prime Minister Junichiro Koizumi has set the stage for this transition, strengthening the ties between the United States and Japan, while also carving out a unique role for Japan that could expand in the near future. The prime minister has been one of the Bush Administration's most enthusiastic supporters. In the wake of 9/11, he dispatched Japanese Self-Defense Force (JSDF) ships to the Indian Ocean in support of Operation Enduring Freedom. In late 2003, Japan sent over 500 members of the ground JSDF to Iraq — the first such deployment of Japanese personnel to a conflict zone since the end of World War II. These two signature foreign policy initiatives enjoyed only lukewarm support among the Japanese public, but Koizumi's popularity provided him with the necessary latitude to largely define Japan's new security role. His successor will almost certainly lack Koizumi's charisma, and will therefore suffer by comparison; but notwithstanding this handicap, the next prime minister is likely to continue to move Japanese politics, and especially Japan's foreign policy, along the trajectory established by the flamboyant Koizumi.
This prospect worries many in East Asia, where people, especially in China and Korea, fear that Japanese assertiveness is a manifestation of, or a precursor to, Japanese nationalism, or even revanchism. Koizumi's visits to the Yasukuni Shrine seem to fit a pattern whereby Japan plays down the gravity of the Imperial Army's abuses during World War II. In another well-publicized instance, a controversy over several Japanese textbooks that overlook Japan's past conduct has contributed to a sense in Asia, particularly in Korea and China, that some Japanese have not fully accepted guilt for the war.
But Japan's emergence as a regional power is welcomed in Washington, where the focus is on burden sharing. So Koizumi's successor will have to strike a delicate balance — satisfying American requests for Japan to become a more active player in regional security while assuaging concerns in key East Asian countries that a greater strategic role for Japan does not pose a threat to their national security.
Burden Sharing, Burden Shedding
Despite the popular conception of Japan as a "pacifist" country that is constitutionally required by Article 9 to pursue a peaceful foreign policy, the Japanese boast one of the most capable militaries on the planet. Japan's defense expenditures trail those of the United States, China and the United Kingdom, but are nearly equivalent to France's military budget. Japan spends more than Russia and more than twice as much as India, the country often seen as a rising power (and a prospective U.S. strategic ally) in the region.
While Japan's budget deficits have been the focus of recent attention, the burden of its defense expenditures is not any greater than that born by other liberal democratic states facing a demographic crunch. Japanese per capita defense spending is comparable to that of Germany and South Korea. Citizens in the United Kingdom pay more than twice as much per person, as do the French. In other words, Japan's defense spending could be expanded if changing strategic circumstances so dictated.
The budgetary costs tell only part of the story. For example, the deployment of U.S. troops in Japan does not pose much of a financial burden to the United States, particularly when considered relative to total U.S. defense spending. Japanese host-nation support covers about 75 percent of the costs of keeping U.S. forces in Japan. Japan claims to pay the United States about $150,000 per U.S. service member on its soil.
But monetary compensation, even if it covered 100 percent of the costs of the troops in question, cannot account for the risks that the United States absorbs through its military presence in Japan and the security guarantee extended to the Japanese. The United States is not in the business of contracting out security services to foreign countries, nor should it be.
If the United States is to focus on a few areas of particular concern related to the War on Terror, especially the Middle East, then U.S. policymakers must seek ways to quietly devolve security responsibilities to wealthy, stable, democratic allies. Japan is at the top of that list. The object of U.S.-Japanese strategic relations should be a more equitable distribution of the burdens of defense between the two allies, with each assuming primary responsibility for its most urgent security interests.
Japan's interests in East Asia greatly exceed those of the United States. Japanese businesses have developed extensive economic ties in the region, and Japanese citizens value friendly, peaceful relations with their Asian neighbors. They are also mindful of potential threats. North Korea's nuclear program, and its ongoing missile development, is an urgent concern. According to some polls, the Japanese public is impatient with the Koizumi government for having not taken a harder line against Kim Jong-il.
Then there is Taiwan. The island is less than 175 miles west of Ishigaki, the southernmost island in the Japanese archipelago, and it sits astride crucial sea-lanes. Military conflict there would disrupt the free flow of raw materials and goods to and from Japan. A Chinese takeover of Taiwan would likely alter the strategic balance in East Asia. Thus, it is not surprising that Japan cares greatly about the ongoing dispute between the People's Republic of China (PRC) and Taiwan.
Japan is well positioned to address the myriad security challenges in East Asia. Its existing capacity for projecting military power beyond its shores is considerable, and could be expanded. Because of Japan's deep and abiding interest in continued peace in the region, and because it has more at stake in the region than the United States, Japan should increasingly take the lead, with the United States moving into a secondary and supporting role.
A Normal Relationship?
To its credit, the Bush Administration has encouraged a more assertive stance on the part of the Japanese government. Although regional fears of a resurgent Japan cannot and should not be dismissed entirely, both the United States and Japan have made some progress in efforts to establish Japan as an independent pole of power in East Asia, a "normal country" that is no longer dependent on a distant patron for its defense. But this process is far from complete, and today Japan's dependency upon the United States alters the public debate, with politicians generating support — or circumventing opposition — by tapping into a feeling of vulnerability.
Consider, for example, the very different circumstances surrounding the first and second Gulf Wars. In 1990, when President George H. W. Bush was assembling an international coalition to expel Iraqi forces from Kuwait, the Japanese took a pass. Facing a public that was unalterably opposed to military participation in the conflict, Tokyo was initially unwilling to make even a serious financial contribution. They ultimately relented, in part due to pressure from the U.S. Congress, providing $13 billion to the war effort.
Twelve years later, Saddam Hussein's Iraq posed no greater threat to Japan than it had in the earlier period. But the second time around, Japan's leaders — and particularly Prime Minister Koizumi — were anxious to prove their loyalty to the United States. "When the United States, an absolutely invaluable ally of our country, is sacrificing itself", the prime minister explained, "it is natural for our country to back the move as much as possible."
The Bush Administration framed the JSDF deployment to Iraq in similar terms. Then-Deputy Secretary of State Richard Armitage said in June 2003 that it was essential that Japan be seen as standing side-by-side with the United States in the War on Terror, and expressed his hope that Japan would decide to put "boots on the ground" in Iraq. Tokyo's primary interest, it could easily be interpreted, was not in bringing stability to Iraq, per se, but rather in maintaining good relations with the United States.
While a majority of Japanese disapproved of the U.S. attack on Iraq in 2003, opposition to their government's support of postwar reconstruction was far more muted. Koizumi even managed to stare down public opposition in December 2005, when he extended the legislative mandate for the Japanese troops in Iraq. The Iraq deployment has not been a dominant issue in the minds of most Japanese voters. Even so, a smart politician knows when not to push his luck: Koizumi announced in June that the Japanese contingent would be withdrawn from Iraq, and all JSDF personnel were pulled out in July.
Koizumi's ability to sustain the mission in Iraq for as long as he did reflects a delicate political balancing act. Japanese troops were posted in a relatively peaceful area near the southern Iraqi city of Samawah. Their assignment, the Japan Defense Agency explained, focused on "humanitarian and reconstruction assistance" and was "designed solely to help the people of Iraq in their attempt to rebuild their own country." The Japanese safe-haven was essentially carved out by Dutch, and later British and Australian, combat forces.
Koizumi sensed that satisfying the United States, even if it meant risking the lives of Japanese soldiers, was a fair bargain just so long as those risks didn't materialize into actual casualties. Although the prime minister's advocacy of the JSDF mission in Iraq did not hurt him politically, it would have been far harder for Koizumi (or any future Japanese leader) to maintain such a stance if Japanese troops were subjected to the chaos and violence that confronts American forces every day. If the Japanese public was genuinely supportive of the mission, if the deployment revealed a sense of shared strategic purpose or was seen as advancing genuine Japanese national interests, then the Japanese mission in Iraq would have been both useful and significant. As it was, the troops were merely symbolic. Koizumi's decision to risk some political capital, as well as time and attention, rallying a modicum of public support for an exceedingly modest, even token, military deployment seems a case of misplaced priorities.
These sentiments are reflected in public opinion polls that show the Japanese wanting to be actively engaged in world affairs, but more focused on challenges and threats in East Asia than the Middle East. In April 2005, the Mainichi Shimbun, echoing public sentiments, warned that the prime minister was not "making sufficient effort to improve Tokyo's relations with Beijing and Seoul." In other words, Koizumi invested his attention, and Japan's military resources, in a distant operation in Iraq, even as the Japanese public remained focused on genuine security issues much closer to home.
It is for this reason that the Iraq case should be seen as an anomaly, not as a harbinger. U.S. pressure on Japan to become involved in peripheral, out-of-area missions could lead to tensions in the alliance, particularly while regional threats fester and grow.
Take, for example, the case of North Korea. The leading regional security challenge of the past decade has been created by the Clinton and George W. Bush Administrations' inability to prevent North Korea from developing offensive military capabilities, including both nuclear weapons and the ballistic missiles that could some day deliver these weapons to Japan or beyond.
The Democratic People's Republic of Korea's (DPRK) various weapons programs have been of concern for Americans for some time, but they pose a far more urgent threat to Japan. Furthermore, the Japanese have still other reasons for distrusting Kim and his duplicitous regime: the DPRK refuses to account fully for the abduction of Japanese citizens in the 1970s and 1980s. Continued strong opposition within Japan to the use of the military for offensive ends suggests that unilateral pre-emptive action by Japan against North Korea, for example, is highly unlikely. On the other hand, it is unrealistic to expect that Tokyo would wait for U.S. permission to respond to a direct attack. It is only slightly more plausible that the Japanese would refrain from using force in response to credible evidence of an imminent threat.
Following the North Korean missile test in July, chief cabinet secretary, Shinzo Abe, a leading candidate to replace Koizumi as prime minister, hinted that the constitutional restrictions on the use of force would not prevent Japan from waging pre-emptive attacks against North Korean missile sites. "If we accept that there is no other option to prevent a missile attack", he told reporters, "there is an argument that attacking the missile bases would be within the legal right of self-defense. I think we need to examine this from the perspective of defending the Japanese people and nation."
Short of pre-emptive strikes, a Japanese military, operating independently of the United States, could deter North Korea from attacking Japan. An independent and empowered Japan might also succeed in convincing the DPRK to abandon its nuclear ambitions. The potential gains are speculative and Japan's actions will still be constrained by the anti-militarist impulses of the Japanese public, but the prospects for a more credible deterrent or threat coming from a "normal" Japan should be considered relative to U.S. economic and diplomatic pressure, which has been completely ineffective in halting North Korea's bellicosity.
Japanese military power might prove instrumental for dealing with future, more serious challenges to the regional security order. Japan's lingering hostility toward and suspicion of North Korea in the near term pales in comparison with its medium- to long-term concerns of a rising China. The trajectory of China's rise to regional prominence threatens to collide with both Japanese and American interests. The open question is whether all three countries will be able to establish a new strategic balance or whether competition for influence in East Asia will lead to a clash that could threaten the lives of hundreds of millions of people on both sides of the Pacific.
Common economic interests within Asia may lead to China's peaceful integration into the region. Or China could turn away from its current course of political and economic liberalization and revert to economic autarchy imposed by military force. It is even possible that China could become a revisionist power, no longer content to accept regional security configurations in their present form. That could occur even if the PRC holds to a course of economic reform.
Against those unlikely but dangerous possibilities, Japan's neighbors should welcome a potential counterweight to a rising China. Many already do. Attitudes toward Japan vary widely, with Taiwanese, Singaporeans, Filipinos and Malays much more favorably disposed than are Koreans to the notion of a wider security role for Japan. These attitudes could evolve further if China's behavior grows more threatening.
The decades-long U.S.-Japan strategic partnership is changing. Americans are becoming increasingly anxious about the costs and risks of our permanent global military presence. We welcome changes that will allow the U.S. military to step back from its role as the world's policeman, and are looking for ways to devolve security responsibilities and reduce our risk exposure. The Japanese — while retaining a strong anti-militarist disposition — are willing to play a more assertive role. They are anxious for their country to behave, and to be treated as a normal country, that is, as a country responsible for defending its interests. Japanese Self-Defense Forces are already highly capable, and Japanese military capabilities could quickly expand if the security environment grows more threatening.
Japan is a stable and mature democracy. The pre-World War II era, when an imperial Japan attempted to secure an exclusive economic sphere for itself, is long past. The ghosts of World War II cannot be allowed to forever dictate the shape and character of U.S.-Japan relations. Americans and Japanese should welcome a transition away from a patron-client relationship, to one based on shared interests, mutual trust and understanding.
