The Architect of America’s Euroskeptic Turn

Colby’s influence is woven into the fabric of the Trump administration’s foreign policy, moving beyond mere rhetoric into tangible shifts in defense and trade. His worldview, famously outlined in his 2021 book The Strategy of Denial, holds that the United States must prevent any single power from dominating key global regions. While China remains his primary concern, he extends this logic to Europe, fearing that a highly unified EU could ultimately exclude U.S. markets and limit American strategic maneuverability. This perspective has already manifested in the freezing of weapons shipments to Ukraine and a broader push to reduce the U.S. military footprint across the continent.

European officials have begun to react with alarm. Andrius Kubilius, the EU’s defense commissioner, has openly characterized this shift as a calculated attempt to dismantle European unity. While Colby maintains that his demands for increased European defense spending are rooted in a desire for a capable partner, the contradiction remains: by forcing Europe to develop its own independent military infrastructure, Washington may be inadvertently accelerating the very political consolidation that Colby views as a threat to American interests. As the administration continues to flirt with bilateral overtures to individual member states rather than engaging the bloc as a whole, the transatlantic relationship is entering an era defined by suspicion rather than shared values.
