The Opening That Waits

That is the institutional risk at the center of David Sacks and Nick Snyder’s September 28 Foreign Affairs essay, “Japan Is Giving the United States a Chance in Asia.” They argue that Tokyo’s expanding defense effort and regional partnerships offer Washington an opportunity to strengthen its position in the Indo-Pacific—and that insufficient American attention could waste it.

Their argument deserves examination without turning their warnings into accomplished facts. An alliance can lose ambition before it loses its name. But predicting that loss is not evidence that Japan has decided to retreat from the relationship.

The Partner Is Not Spare Capacity

Sacks and Snyder describe Japan’s strategy as reinforcing, rather than escaping, its alliance with the United States. Their central concern is reciprocity: Japanese initiative requires a sustained American response, not merely American appreciation of the benefits.

They recommend wider joint weapons production, closer operational planning, expanded intelligence cooperation and investment in less vulnerable supply chains. These are proposals, not an inventory of completed cooperation. They also show why “pay more” is an inadequate theory of alliance management. A partner can commit resources without gaining the components, information or influence necessary to make those resources useful.

The authors’ framing is explicitly strategic: a stronger Japan can help the United States protect its interests at lower cost and risk. That is a recognizable case to put before Washington. It is also incomplete as a test of whether the partnership works.

Lower cost for one participant does not, by itself, establish lower risk for everyone. Closer military integration should be judged by what it enables both countries to defend, what obligations it creates and who gets to question those obligations. Otherwise, the alliance has found an efficiency. Whether it has found a common purpose remains unresolved.

Put the Risk-Bearers Inside the Plan

Consider one concrete recommendation in the essay: establishing a rotational U.S. military presence on Ishigaki. Sacks and Snyder present this as a way to improve the allies’ strategic position around Taiwan. The proposal also raises questions their strategic rationale cannot settle on its own: what would it mean for local residents, what emergency preparations would accompany it, and how would their concerns affect the decision?

These are questions for evaluating a proposal, not claims that a deployment has been approved or that residents hold a single view. People living where a strategy would operate are participants in its consequences, not empty space on a map.

The same standard applies between governments. Reciprocity requires more than each side contributing something. It requires a usable process for explaining constraints, revising commitments and disagreeing before a crisis compresses the available choices. Consultation that cannot change a plan is mostly a courtesy with meeting minutes.

Sacks and Snyder go further, warning that a loss of confidence in Washington could prompt profound changes in Japanese policy, including a pursuit of nuclear weapons. Those are conditional forecasts, not announced Japanese decisions. The case for maintaining a serious partnership need not depend on accepting that entire chain of escalation.

A narrower conclusion holds: neither government should treat the other’s present willingness as an indefinitely renewable resource. The practical test is whether proposed cooperation comes with accountable commitments, realistic delivery arrangements and meaningful influence for the people expected to carry its risks.

An alliance that accommodates that feedback can become more durable without demanding unanimity. One that merely counts contributions may discover the difference too late: the partner is still present, but no longer willing to offer quite so much.
