it is not only our values that matter, but the military might that backs them up. Truly, in international affairs, behind all questions of morality lie questions of power. Humanitarian intervention in the Balkans in the 1990s was possible only because the Serbian regime was not a great power armed with nuclear weapons, unlike the Russian regime, which at the same time was committing atrocities of a similar scale in Chechnya where the West did nothing; nor did the West do much against the ethnic cleansing in the Caucasus because there, too, was a Russian sphere of influence. In the Western Pacific in the coming decades, morality may mean giving up some of our most cherished ideals for the sake of stability. How else are we to make at least some room for a quasi-authoritarian China as its military expands? (And barring a social-economic collapse internally, China's military will keep on expanding.) For it is the balance of power itself, even more than the democratic values of the West, that is often the best preserver of freedom. That also will be a lesson of the South China Sea in the twenty-first century--one more that humanists do not want to hear.
