After Vietnam, American power grew quieter.
In Latin America through the 1970s and 1980s, the United States supported authoritarian regimes so long as they aligned with American interests. Elections became optional. Human rights conditional. Chile, El Salvador, Guatemala, Argentina. Sovereignty was respected in form, overridden in practice. Influence traveled through intelligence cooperation, arms transfers, and financial institutions.⁹ These arrangements were often accepted by local elites—and sometimes by populations exhausted by instability—because they promised order, growth, or protection against worse alternatives.
After September 11, the language shifted again. Afghanistan and Iraq were not colonies. They were missions. But the structure was familiar: client governments, redesigned security forces, permanent bases, contractors replacing administrators. Political systems built under supervision. Withdrawal always promised, never decisive.¹⁰ Conditional sovereignty persisted, justified now by urgency rather than ideology.
What distinguishes the present moment is not the return of imperial instinct. It is the erosion of its disguise.
Previous administrations practiced conditional sovereignty while insisting—often sincerely—on the language of partnership. The system depended on restraint, predictability, and the appearance of mutual consent. Trump discarded that vocabulary. He spoke of allies as dependents, territory as assets, guarantees as transactions. What earlier administrations implied through doctrine and budget pressure was now stated plainly.
That bluntness did not create American power. It revealed its grammar.
Allies recognize the sound because they have heard it before. Europe hears it through the memory of postwar dependence. Canada hears it through proximity. Mexico hears it through a border that has always functioned less as a line than as a lever. Even states far from the Atlantic hear it, because American power has always been global in consequence, if not geography.
What has changed is how they respond.
Where earlier eras relied on trust in American stewardship, the contemporary response is procedural insulation: procurement frameworks, trade diversification, legal embedding. The same paperwork once used to project power is now being used to limit exposure to it. SAFE agreements, supply-chain redundancy, and regulatory harmonization are not rejections of American leadership. They are adaptations to its volatility.
When sovereignty is treated as conditional, states seek to meet the condition—or escape it. This is not rebellion. It is recalibration.
Conditional sovereignty works only so long as the dominant power is predictable. Once predictability fades, the condition itself becomes intolerable.
That is the quiet danger of the current era. By speaking the logic of dominance too clearly, the United States may be accelerating the erosion of the system it built. Power that once felt stabilizing now feels extractive. Guarantees once assumed now feel provisional.
Empires rarely collapse when challenged directly. They erode when their paperwork stops persuading the people asked to sign it.
