In defense terms, America’s “pivot to Asia” is not a single move, but a weaving of initiatives—with overlapping bi-, tri-, quadri- and multilateral deals—to create an ever-thickening lattice on China’s periphery. Some deals are modest; many are uncertain if tested in war. But they amount to the “fortification of America’s forward defense perimeter in the western Pacific.”…Despite its pacifism, Japan is greatly boosting defense spending. American marines in Okinawa are practicing how to scatter and defend the islands and sea passages. The next link, Taiwan, is under intense strain, given China’s aim to retake the self-governing island by force if necessary. America may soon announce the first “drawdown” of weapons from its own arsenal, pre-emptively strengthening Taiwan much as it has armed Ukraine. The Philippines, the next link, is weaker but has agreed to give America access to nine bases in the country; in return America is helping to beef up its forces….

America is devising ways to disperse its jets in wartime and hardening the defense of Guam. It wants to project more power from Australia, where it rotates air force and marine units. It is working with Britain to supply nuclear-powered submarines to Australia under the aukus deal; the three are also working on new weapons, including hypersonic missiles. Farther afield, the Quad—America, Australia and Japan working with India—is not a formal security grouping, but their navies exercise together. Across the region, American-led war-games are becoming bigger and more sophisticated. Sometimes America’s security arrangements are limited, for instance its new defense deal with Papua New Guinea; or its efforts to help littoral states improve “maritime domain awareness” to, say, curb illegal fishing by Chinese fleets. This, too, helps enmesh America in the region…

China accuses America of building an “Asian NATO”. But the reality is a looser system. America’s friends and allies in the “Indo-Pacific” have no mutual-defense commitments akin to NATO’s Article 5, under which an attack on one is an attack on all, nor integrated multinational commands.
