The U.S. National Security Strategy, unveiled by the Trump administration, presents a vision that prioritizes American influence in the Western Hemisphere and advocates for a more interventionist stance in European political affairs. The document, which builds on the 'America First' doctrine, warns of a 'civilizational erasure' facing Europe and calls for U.S. assistance in addressing what it perceives as Europe's declining trajectory.

A revival of the Monroe Doctrine is proposed, aiming to counter European interference in the Americas, alongside a 'Trump Corollary' intended to restore U.S. preeminence in the region. This includes military actions against drug cartels and reallocating U.S. military resources towards the Western Hemisphere, where the U.S. has reportedly conducted numerous lethal strikes against alleged drug trafficking operations.

In Europe, the strategy's rhetoric has drawn criticism from various officials, including former leaders who liken it to far-right ideologies. The document suggests that the U.S. should foster resistance to current European policies, particularly regarding migration and national identity, and references the controversial 'Great Replacement Theory' as part of its rationale.

The strategy's tone has been described as conciliatory towards Russia, which has led to approval from Russian officials who claim it aligns with Moscow's vision. Notably, the strategy does not identify Russia as a threat to the United States, raising concerns among EU officials about its potential to weaken the West's response to Russian aggression in Ukraine. The document criticizes the EU for hindering U.S. efforts to resolve the conflict in Ukraine and emphasizes the need for the U.S. to restore 'strategic stability' with Russia to benefit European economies.

Furthermore, the strategy advocates for a revival of 'Western identity' and warns that Europe may become 'unrecognizable' within two decades due to economic challenges and civilizational decline. It questions the reliability of certain European nations as allies, citing concerns about their military and economic capabilities, while expressing support for 'patriotic European parties' and encouraging a resurgence of national spirit among U.S. allies in Europe.

As the EU engages in discussions with the Trump administration regarding a peace deal in Ukraine, some officials have reaffirmed their commitment to the U.S. as a key NATO ally, although they express reservations about the strategy's focus on issues of freedom of expression and societal organization. Polish Prime Minister Donald Tusk emphasized the importance of Europe as an ally to the U.S., while former Swedish Prime Minister Carl Bildt criticized the document for aligning with extreme right ideologies.

Democratic representatives in Congress have voiced concerns that the strategy could damage U.S. foreign relations, with some labeling it detrimental to America's global standing and a departure from long-standing value-based leadership. The strategy also proposes increased military engagement in regions such as the Caribbean and eastern Pacific, particularly concerning alleged drug trafficking and potential actions in Venezuela.
