senior Pentagon official tells Manila the US is 'digging in' but expects allies to step up

What 'digging in' actually means

At the same time, Colby drew a sharp line between partnership and dependency. In remarks reported across multiple outlets, he said Washington wants allies and partners who are willing to invest in their own armed forces rather than rely on the United States to underwrite their security. The distinction matters in capitals from Tokyo to Canberra, where defence budgets have been creeping upward but governments still look to Washington for hard-power guarantees.

The Philippines has emerged as one of the most visible testing grounds for that new compact. Manila hosts a rotating presence of US forces under the Enhanced Defense Cooperation Agreement and has granted expanded access to several bases facing the South China Sea. Ferdinand Marcos Jr. has moved closer to Washington and further from Beijing since 2022, and Philippine planners are weighing how to modernise an armed force still shaped by counter-insurgency missions.

Why the Philippines sits at the centre

Chinese behaviour in the South China Sea has provided political cover for that shift. Philippine vessels have reported near-collisions with Chinese coast guard ships, and Beijing has steadily expanded its presence around disputed reefs and shoals. Colby's remarks came against that backdrop, and they signal that Washington expects Manila and its neighbours to spend more on platforms, maritime domain awareness and joint exercises even as the US commitment is reaffirmed.

Southeast Asia more broadly is the operational focus. Indonesia, Vietnam and Malaysia do not have formal alliance treaties with the United States, but all are watching the same flashpoints and all are courted by Beijing's economic and diplomatic outreach. Colby's message is calibrated for that middle band of states: the US will remain engaged, but it will not subsidise free-riders indefinitely. Allies and partners, he suggested, should treat the relationship as a two-way street with real defence budgets attached.

The wider Southeast Asian picture

The speech lands in a wider doctrinal conversation in Washington about burden-sharing. Officials in successive administrations have pushed European and Asian partners to lift defence spending toward two percent of GDP and beyond. What is newer is the explicit coupling of that ask with the language of partnership rather than alliance obligation. In Colby's telling, the United States is not retreating but is also not offering an open tab.

Critics of the approach warn that demanding more from partners can be self-defeating if the political will in allied capitals is shallow, or if the security environment deteriorates faster than procurement cycles can respond. Supporters counter that the post-Cold War assumption of American primacy is fading and that allies must be made co-owners of regional stability rather than beneficiaries of it. The Manila speech is a public iteration of that debate, delivered in one of the regions where the consequences are most concrete.
