NEW YORK – One way to look at the growing military tensions over a few tiny islands in the East China Sea is to see in recent events a straightforward case of power politics. China is rising, Japan is in the economic doldrums, and the Korean peninsula remains divided.

It is only natural that China would try to reassert its historical dominance over the region. And it is just as natural for Japan to feel nervous about the prospect of becoming a kind of vassal state (the Koreans are more accustomed to this role, vis-à-vis China).Being subservient to American power, as Japan has been since 1945, was the inevitable consequence of a catastrophic war. Most Japanese can live with that. But submission to China would be intolerable.And yet, because East Asian politics remains highly dynastic, a biographical explanation might be just as useful. Shinzo Abe, the Japanese prime minister, is the grandson of Nobusuke Kishi, once the top industrial bureaucrat of wartime Japan. Imprisoned by the Americans as a war criminal in 1945, Kishi was released without trial at the beginning of the Cold War, and was elected Prime Minister as a conservative in 1957.Kishi was a nationalist with fascist tendencies during the 1930’s and 1940’s. After the war, an equally deep aversion to Communism made him a staunch ally of the United States; Richard Nixon became a close friend. His lifelong quest was to revise the pacifist Japanese constitution, written by the Americans just after the war, and turn Japan into a proud military power once more.Abe’s greatest wish is to complete the project that eluded his grandfather: abandon constitutional pacifism and bury the war crimes of Kishi’s generation, while remaining allied with the US against China. As a right-wing nationalist, Abe feels compelled to resist the dominance of China, if only rhetorically for the time being.One of Kishi’s greatest Cold War allies – apart from Nixon – was the South Korean strongman President Park Chung-hee, who came to power in a military coup a year after Kishi resigned as prime minister. Park, too, had a dubious wartime career. Under the Japanese name of Takagi Masao, he served as an officer in the Japanese Imperial Army. He graduated from a military academy in Manchuria, where Kishi had once ruled over an industrial empire that was built on Chinese slave labor.Like Kishi, Park was a nationalist. But, apart from his sentimental wartime connections to Japan, his anti-Communism was incentive enough to continue warm relations with the imperial power that had brutally colonized Korea for a half-century. Park Geun-hye, South Korea’s current president, is his daughter.Park Geun-hye adored her father at least as much as Abe loved his grandfather, but the result of her dynastic connection is the opposite of Abe’s. To be seen as a Korean nationalist today, she must distance herself from some of her father’s political ties, especially his links with Japan. Though still admired by many South Koreans for rebuilding the country from the ruins of war, his legacy, like that of many members of the old conservative elite, is tainted by wartime collaboration. So his daughter must confront Japan over territorial disputes, to avoid inheriting the stigma of her father’s colonial past.The case of the current Chinese leader, Xi Jinping, is perhaps the most complicated of the three. His father, Xi Zhongxun, was one of the top leaders of the Communist revolution. A guerilla leader in the war against Japan, he helped to defeat Chiang Kai-shek’s Nationalists in China’s civil war, became a member of the Central Committee, and then chief of propaganda, Vice Premier, and Governor of Guangdong.An impeccable Communist career, one might think, giving his son no need to distance himself or to complete a frustrated ambition. But Xi’s nationalism, too, has a history.Chairman Mao’s main aim was to consolidate his revolution at home. His nationalist credentials were so impressive that he could afford to be relatively easy on former enemies. Territorial disputes over unimportant islands could be laid to rest. He did not even bother to reclaim Hong Kong from the British.It was only when Deng Xiaoping opened the door to trade with capitalist countries that anti-Japanese sentiments were deliberately stirred up. Neither Marxism nor Maoism could be used to justify China’s joining the capitalist world. This left an ideological vacuum, which old-fashioned nationalism soon filled. The more the leadership opened up the Chinese economy, the more it stoked popular anger over past wrongs, especially those committed by Japan.The man who was most responsible for Deng’s Open Door policies was none other than Xi’s father, Xi Zhongxun. Always a pragmatic Communist, the elder Xi had been the target of several purges under Mao, when relative moderates were frequently denounced as counterrevolutionaries.
