Prime Minister Sanae Takaichi’s recent landslide victory wasn’t merely a domestic triumph for Japan; it was a resounding win for U.S. national security interests, particularly in the Indo-Pacific.
President Trump has often been painted as skeptical of alliances, yet Japan stands out as the vital, unshakeable partner amid the relentless rise of an aggressive, assertive and authoritarian China.
In his first term, Trump cultivated a close relationship with the late Prime Minister Shinzo Abe, assassinated in 2022. The two leaders shared not just a love of golf, but a clear-eyed view of China as the main threat to regional stability.
China’s rise inspired Abe’s vision of a Free and Open Indo-Pacific (FOIP) strategy, with Japan pledging itself to work with like-minded regional partners to uphold freedom of navigation, territorial and maritime sovereignty, and quality infrastructure.
Trump remains pledged to these same tenets. The latest U.S. National Security Strategy (NSS), released in November, makes it crystal clear: preserving a free and open Indo-Pacific, securing supply chains, and ensuring access to critical minerals are non-negotiable for American security and prosperity.
The NSS also demands that economic vitality must be accompanied by a “robust and ongoing focus on deterrence to prevent war in the Indo-Pacific” and implicitly acknowledging the catastrophic fallout from any Chinese move against Taiwan.
That's why the Trump administration's approval of the record-breaking $11+ billion arms sale to Taiwan in December was not just prudent—it was essential.
Prime Minister Takaichi, elevated to the premiership last October, carries forward Abe’s legacy with determination. Her early rapport with President Trump got off to a good start last year during his visit to Japan.
Trump predicted then that the pair would have a “fantastic relationship”, telling Takaichi she could have “any favors you need, anything… to help Japan."
The seeming special status of Japan in the eyes of President Trump was confirmed in January during a meeting between Secretary of Defense Pete Hegseth and Japan’s Defense Minister Shinjirō Koizumi. Koizumi had been the first Japanese defense minister to speak at the Honolulu Defense Forum.
Hegseth praised the bilateral relationship as “remarkable” and endorsed Japan’s accelerating defense spending, which will soon hit the 2% of GDP target two years ahead of schedule. This addresses the NSS’s demand that allies “must step up and spend—and more importantly do—much more for collective defense.”
Hegseth’s remarks on the America First doctrine help explain Japan’s status.
“America first, yes, but it doesn't mean America alone,” he said. The United States stands shoulder to shoulder with partners who invest in their own security and pull their weight. Japan is doing exactly that—unlike some European allies long criticized for underinvesting after decades of complacency.
The U.S.–Japan alliance, therefore, is strong. But it has yet to face its greatest test.
The war with Iran that began on February 28 underscores how interconnected today’s security environment has become. A widening Middle East conflict strains U.S. force posture, energy markets, and global supply chains—precisely as tensions with China intensify in the Indo-Pacific. In that context, a capable and reliable ally like Japan becomes not just important, but indispensable.
The emerging China-Russia-North Korea axis, orchestrated from Beijing, seeks to dismantle American preeminence in the Indo-Pacific and Japan’s “Free and Open” vision. China is growing more aggressive, as evidenced in December when Chinese J-15 fighters locked radar on Japanese aircraft near Okinawa, drawing international condemnation as a dangerous provocation.
North Korea, for its part, continues to fire hypersonic and intermediate-range ballistic missiles into the Sea of Japan in violation of UN Security Council resolutions and constituting a legitimate threat to Japan’s mainland.
Japan’s strategic position makes it irreplaceable and crucial to confronting these threats in partnership with the U.S. and other like-minded partners.
U.S. bases in Japan and South Korea anchor America’s forward posture. Joint bilateral drills with Japan and multilateral exercises with Australia, the Philippines, and others serve as a deterrent to its antagonists while building interoperability and reinforcing stability.
Japan’s pacifist constitution limits it to defensive military operations, but in December, Prime Minister Takaichi signaled unequivocally a commitment that Japan’s Self-Defense Forces will support U.S efforts to protect Taiwan, should China invade the island.
This yielded a furious backlash in Beijing. The howls of condemnation only served to underscore that Takaichi was right.
Early concerns about Trump's second term fraying Asian alliances have faded. Trade surplus rhetoric has yielded to stark geopolitical truths. America needs Japan—its most reliable, capable partner in Asia. President Trump understands this, and so does China.
In an era of courage meeting consequence, the U.S.-Japan bond isn't just enduring. It's the linchpin of a free and open Indo-Pacific.
Editor's Note: For decades, former presidents have been all talk and no action. Now, Donald Trump is eliminating the threat from Iran once and for all.
