Paying Billions for US Protection While Building Alternatives

In September 2025, Japan agreed to a $550 billion investment deal with the United States. The terms were extraordinary for a treaty ally: Japan would borrow money to fund US government-selected projects — antibiotics plants, nuclear facilities — with profits split 50/50 until Japan recouped its capital, then shifting to 90% for the US and 10% for Japan ^[1]. Commerce Secretary Howard Lutnick described the arrangement in blunt terms.

After that, it's 90/10, in favor of America. — Howard Lutnick

The asymmetry was the point. Japan accepted it in exchange for a 15% baseline tariff rate.

For their country's perspective, it's a good deal. — Howard Lutnick

This is what paying for the American alliance now looks like in dollars. But the same Japan that wrote that check was, within months, signing military cooperation pacts with the Netherlands and New Zealand — agreements designed to diversify its security partnerships beyond Washington ^[2].

The defence Acquisition and Cross Servicing Agreement sets out how logistical support, including the provision of supplies and services, will be managed when the New Zealand Defence Force and the Self-Defence Forces of Japan operate together. — Judy Collins

And in November 2025, Japan signed a Reciprocal Access Agreement with the Philippines — the first authorization of Japanese military deployment there since World War II ^[3]. Philippine Defence Secretary Teodoro called it a template for similar pacts with Canada, France, and New Zealand. The two tracks were visible in a single country, not as contradiction but as simultaneous strategy. The paying track runs across the region. South Korea pledged $350 billion in US investments, including $150 billion for shipbuilding, in exchange for tariff reductions from 25% to 15% ^[4]. Commerce Secretary Lutnick framed the choice as binary.

The Japanese signed the contract. — Howard Lutnick

Taiwan committed $250 billion in US investments — including $100 billion to $165 billion from TSMC — plus $85 billion in energy and aircraft purchases, securing a 15% tariff rate ^[5]. Separately, under direct US pressure, Taiwan is increasing defense spending to 5% of GDP by 2030, adding $40 billion in funding through 2033 ^[6]. Taiwan is paying twice: once for tariff relief, once for the defense commitment itself. Indonesia signed a reciprocal trade agreement in February 2026, reducing tariffs from 32% to 19% in exchange for 50 Boeing aircraft and massive agricultural import commitments ^[7]. The sums are large enough to be their own argument. But what distinguishes this moment is not the size of the payments — allies have always shouldered costs — but the explicitness with which Washington has priced the guarantee. In April, Indo-Pacific Command chief Admiral Paparo told Taiwan it needed to pass a NT$1.25 trillion defense budget, stating the condition plainly.

We can't want Taiwan's defense more than they want it themselves. — Samuel Paparo

President Trump had already made his position clear ^[8].

it is up to President Xi how he deals with Taiwan — Donald Trump

At the Ankara NATO summit in July, Defense Secretary Hegseth made the same logic structural ^[9].

Going forward, our annual NATO dues will be contingent on other countries meeting their defense spending targets. — Pete Hegseth

And when the US-Taiwan trade pact was signed, USTR Jamieson Greer fused the two categories entirely ^[5].

President Trump's leadership in the Asia-Pacific region continues to generate prosperous trade ties for the United States with important partners across Asia, while further advancing the economic and national security interests of the American people. — Jamieson Greer

These were not dog whistles. They were invoices. And allies received them as such. The building track is the response. Japan's pacts with the Netherlands, New Zealand, and the Philippines are one strand. South Korea and Japan are deepening bilateral defense ties — joint search-and-rescue exercises, AI cooperation, defense equipment transfers — while maintaining US-encouraged trilateral coordination ^[10]. India is deepening defense ties with Indonesia and Japan, including potential BrahMos missile sales to Indonesia and supply-chain resilience cooperation with Tokyo ^[11]. Australia and India are expanding strategic defense and energy ties, updating defense statements and developing a maritime security roadmap ^[12]. The Japan-Philippines Reciprocal Access Agreement is explicitly a template for more. None of these pacts replaces the US alliance. Each is bilateral or minilateral, limited in scope, and no ally has suggested it would prefer a Japanese or Indian security guarantee to an American one. But taken together, they form a web that reduces the catastrophic risk of US withdrawal — a parallel architecture built not in opposition to Washington's alliance system but in anticipation of its possible erosion. The evidence does not fully establish that the explicitness of the pricing is what drives the building. The causal chain — explicit conditioning creates perception of unreliability, which creates demand for alternatives — is analytically coherent, and the timing is suggestive: the Japan-Philippines RAA was signed in November 2025, after the Japan-US $550 billion deal was announced in September; the Japan-Netherlands and New Zealand pacts came in December; the South Korea-Japan defense deepening accelerated through mid-2026. But correlation is not causation, and allies have been diversifying security partnerships for decades. What is new is the pace and the breadth — and the fact that the same countries writing the largest checks are the ones building the fastest. The pattern is not uniform. India is the most significant exception: Commerce Minister Goyal explicitly refused to be pressured by US tariff deadlines.

We don’t do deals in a hurry, and we don’t do deals with deadlines, with a gun on our head. — Piyush Goyal

India is resisting the paying track while actively building the architecture — deepening ties with Indonesia, Japan, Australia, and the Philippines ^[11][12][13]. Vietnam is diversifying trade without bundling security: it secured a US tariff reduction from 46% to 20% through a reciprocal trade agreement ^[14] while simultaneously upgrading relations with the EU to a Comprehensive Strategic Partnership — the EU's first in Southeast Asia — explicitly framed as diversification amid tariff pressure from Washington ^[15]. Indonesia took the trade deal and the Boeing purchase but its Foreign Ministry immediately pushed back against blanket US overflight access, warning it could entangle Jakarta in South China Sea conflicts ^[16].

On the issue of overflight, regulatory mechanisms are still being carefully reviewed, with national interests, Indonesia’s airspace sovereignty and the principles of its free and active foreign policy serving as primary foundations. — Ministry of Foreign Affairs of Indonesia

These are partial exceptions that confirm the dominant pattern by departing from it: most allies are running both tracks, not choosing one. The pressure is compounded by China, which is pursuing roughly 20 trade deals — tariff reductions with Canada, zero tariffs for 53 African nations, CPTPP membership, free-trade proposals with the EU and Gulf Cooperation Council — specifically to exploit the uncertainty created by US tariff policy ^[17]. Allies cannot afford to lose either the US security umbrella or Chinese trade access, so they pay for one while hedging against the other. What the pattern suggests is that the payment and the architecture-building reinforce each other. The more Washington prices its guarantees as trade concessions, the more it demonstrates that those guarantees are contingent — and the more allies invest in alternatives that make the contingency survivable. Washington's transactionalism is not failing: allies are paying. But the payment is not buying loyalty in the way it once did. It is buying time — and allies are using that time to build. If that inference holds, the explicitness that extracts the payment is also what makes the alternative necessary.
