Guam on the Brink: A Critical Node in US Defense Facing Escalating Threats
As I conclude nearly four decades of military and public service, including as lieutenant governor of Guam, a line from the 1986 Crowded House song Don’t Dream It’s Over keeps returning to me: “Trying to catch a deluge in a paper cup.” For Guam — a United States territory and cornerstone of American power projection increasingly under threat from both North Korea and China — that metaphor appears increasingly, and disturbingly, apt.
Guam’s Strategic Importance
Guam, a westernmost U.S. Territory in the Indo-Pacific, has long been a valuable strategic asset . Its location—closer to Beijing than to Hawaii—makes it ideal for U.S. Power projection amid rising tensions in the South China Sea, Taiwan Strait, and Korean Peninsula . The island anchors U.S. Air, naval, logistics, and sustainment operations across the Western Pacific, enabling power projection into the Philippine Sea and beyond.
Andersen Air Force Base provides a geographically secure platform for long-range bomber operations, even as Naval Base Guam supports undersea presence—a cornerstone of deterrence . These installations transform Guam into an operational hub essential to American power projection.
Escalating Threats from North Korea and China
Recent open-source analysis underscores growing concerns. While the United States has increased investment in Guam’s defenses, the pace and sophistication of long-range strike threats are advancing rapidly. In 2017, North Korea threatened strikes on U.S. Military targets in Guam , and in 2025, North Korea launched a “new” intermediate range ballistic missile that “will reliably contain any rivals in the Pacific” . China has as well unveiled ballistic missiles capable of reaching Guam and launched its first long-range missile into the Pacific in 2024 .
The threat from the People’s Liberation Army is multi-domain, encompassing ballistic and cruise missiles, cyber operations, and space-based intelligence . The DF-26 intermediate-range ballistic missile is one element of a broader strike complex.
Defensive Measures and Challenges
To shield Guam, Washington has finalized plans for an Enhanced Integrated Air and Missile Defense (EIAMD) system . The $8 billion EIAMD will incorporate Aegis systems, Standard Missile 3 and 6 interceptors, and radar systems .
However, Guam faces significant challenges. Missile defense systems are still being fielded, and the island’s only public hospital dates to the 1970s. Civil defense siren coverage is incomplete, and food and fuel reserves are finite. Super Typhoon Mawar in 2023 exposed infrastructure fragility, disrupting power, water, and medical services .
Congressional Action and Future Outlook
The Fiscal Year 2026 National Defense Authorization Act authorizes measures for Guam, including housing and utility allowances and funding for elements of the Guam Defense System. However, it also removed over $1 billion in previously proposed funding for submarine-related infrastructure .
Closing the gap between threat and defense requires prioritizing rapid integration of fieldable missile defense systems, accounting for the civilian dimension of conflict, treating air and port infrastructure as recoverable, and leveraging the Guam National Guard. Guam needs urgency reflected in the pace and scale of preparation. Delay is not neutral—it compounds risk.
