“Moshitora,” Japanese shorthand for “what if Trump?,” first emerged in the run-up to the 2016 U.S. election, as policymakers and business leaders in Tokyo tried to make sense of an unpredictable candidate.

The phrase resurfaced in early 2024 as Donald Trump’s campaign regained momentum. This time, it carried more than curiosity. It reflected strategic caution and genuine unease. What would a second Trump presidency mean for Japan’s security, its economic ties, and its role in the Indo-Pacific?

The US-Japan alliance has entered a new phase that looks beyond defense alone.

The question mattered bigly. Since former Prime Minister Shinzo Abe’s assassination in 2022, Japan has had to manage its alliance with Washington without the personal rapport Abe cultivated over decades. Trump’s first term had already shown how quickly supply chains could become instruments of strategic power and how fast economic policy could merge with national security.

For decades after the Cold War, Western policymakers assumed deep trade ties would soften geopolitical tensions. If nations became economically intertwined, conflict would grow too costly to sustain. That assumption collapsed. Supply chains did not reduce rivalry. They became tools of leverage instead.

Technology, once treated mainly as an engine of economic growth, became a strategic asset. Materials long confined to commodity markets — lithium, cobalt, nickel, and rare earths — moved to the center of national security planning.

The consequences reached far beyond trade policy. Industries once taken for granted became strategic pressure points. Governments began to see commercial flows not as neutral exchanges, but as levers of power. Control over production, processing, and access could shape the balance of global influence.

Trump’s first administration accelerated that reckoning. Washington had to confront dependencies it had ignored for too long. Over the next several years, policymakers turned instinct into structure. Alliances no longer looked like military arrangements alone. They began to function as economic security networks built around trusted supply chains, resilient manufacturing, and reliable access to critical materials.

The results are now visible. In October 2025, the U.S. and Japan signed a framework to secure supply chains for rare earths and critical minerals, with the stated goal of reducing dependence on China’s dominant processing capacity.

Africa shows the stakes even more clearly. In early 2026, Glencore entered a nonbinding agreement with the U.S.-backed Orion Critical Mineral Consortium to sell 40% of its Mutanda and Kamoto copper and cobalt mines in the Democratic Republic of Congo.

These mines rank among the world’s largest producers of metals essential to next-generation technologies. The deal aims to diversify supply beyond China’s orbit.

Across Africa, Washington has deepened partnerships to strengthen supply chains for essential commodities, while Japan has pursued its own ties with resource-rich nations.

These efforts go beyond securing raw materials. They concern industrial resilience, strategic autonomy, and influence over the technologies that will define the next era of power. Countries now face a hard question: Who offers long-term commitment, and who merely shows up to extract what it needs?

Japan’s approach reflects foresight. Its economic security policies — diversifying supply chains, investing in semiconductors, and deepening ties with African and Southeast Asian resource producers — show a clear understanding that industrial capacity underwrites national power. In some respects, Tokyo saw this shift coming before Washington did.

The U.S.-Japan alliance has entered a new phase that looks beyond defense alone. Who will build together, mine together, and secure the industrial base behind technological competition? The choices nations make now will help determine which economies and militaries remain resilient enough to compete in the years ahead.

“Moshitora” began as a phrase about a single American election. Its return in 2024 looks, in hindsight, like a warning Japan had already begun to heed. The question now is whether Washington will answer with the same clarity, persistence, and long-term vision.
