It was pretty surreal to hear Leon Panetta warning of an actual war between China and Japan, arriving in Tokyo just as the two Asian powers are facing off over contested islands in the East China Sea. What made it so incongruous is that despite the obvious lingering enmities from World War II (which for China really started in 1937, or maybe even 1931), in the current world conflict that we call World War 4, warfare is explicitly portrayed even by Pentagon planners as an instrument of globalization—bringing the light of "free markets" and "integration" to benighted regions of the globe that continue to resist their lures. Warfare is now "asymmetrical," posing a single superpower and its allies against "terrorists" and insurgents, or at the very most against "rogue states." The old paradigm of war between rival capitalist powers has seemed pretty irrelevant for the past generation. In the Cold War with the Russians, the superpowers manipulated proxy forces while the US aimed for strategic encirclement of the rival power. In the New Cold War with China that is now emerging, the US again seeks strategic encirclement, and while there aren't any proxy wars being waged (no contemporary equivalent of Vietnam or Angola or Nicaragua), Japanese and South Koreans should beware of their governments being entangled in Washington's containment strategy—as Panetta's own comments acknowledge, games of brinkmanship can get out of control. And, as we noted, even as he made his warning, he was in Japan to inaugurate a new anti-missile radar system, ostensibly designed to defend against North Korea, but certain to be perceived in Beijing as a part of the encirclement strategy...
