For over 80 years, the US and Europe shared a bond centered on mutual defense and democratic principles. However, the recent US National Security Strategy (NSS) under Trump indicates a pivot away from these commitments, highlighting instead a more nationalist approach that questions the legitimacy of international norms. Statements from US officials, such as Vice-President JD Vance, indicate that threats to democracy in Europe are internal rather than external, prompting urgent discussions among European leaders about the viability of existing alliances. The NSS signals a reassertion of sovereignty against what it describes as 'intrusive transnational organizations', suggesting that the US may no longer assist Europe as it has in the past. As Europe contemplates its role amid these changes, the push for national independence and increased defense spending gains traction, urging a reconsideration of its relationship with the US while facing rising security challenges from rivals like Russia and China. The path forward remains uncertain, and Europe must navigate these complexities carefully to define its own future.
