US President Donald Trump’s foreign policy can no longer be dismissed as chaos or personal improvisation. Rather, it is a conscious effort to dismantle the post-1945 international order and replace its rules with a simpler, harsher world governed by spheres of influence, in which deals are more important than alliances, and power is more important than the law.
The latest US National Security Strategy is no technical document. It is a declared rupture from the idea of Western leadership. This includes its traditional role as global policeman and guarantor of the international system. Instead, the US presents itself as a great power intent on fortifying its influence, shrinking its commitments, and penalising those who cross its red lines or approach its backyard. What goes on elsewhere, the document implies, is none of Washington’s business.
The most dangerous aspect of this strategy lies not in what it says, but in what it ignores. Russia is hardly mentioned, and despite it being the largest conflict in Europe since 1945, the war in Ukraine is reduced to a marginal conflict unworthy of anchoring US policy. This omission is not accidental; it stems from the logic of spheres of influence. Ukraine does not fall within America’s vital domain, and Europe’s security is seen as more of a burden than a strategic priority.
Trump’s redefinitions
The American message is unmistakable: Europeans must defend themselves and resolve their own problems, or accept settlements imposed over their heads—even if that entails the consolidation of permanent Russian influence in Eastern Europe. The old continent must therefore face up to this new US-led redefinition of its place in the international order: that of subordinate, rather than a partner.
At the same time, the notion of what constitutes a ‘real’ threat to the United States is being redefined, reflecting the country’s increasing insularity. Mass migration, narcotics, transnational crime, and social disintegration are now framed as existential dangers, while major wars and conflicts are footnotes.
In a sense, this shift translates as a return to the 200-year-old Monroe Doctrine, elucidated in 1823 by US President James Monroe, which holds that any intervention in the political affairs of the Americas by foreign powers is a potentially hostile act against the United States. It asserts that the Western hemisphere is a sphere of influence and American interest.
