Following Trump’s re-election and his statement on NATO – “if you are not going to pay your bills, we are not going to defend you” (NBC News, 2023) – along with JD Vance’s remarks at the Munich Security Conference and their tense Oval Office meeting with Zelensky, a strong response from EU countries became inevitable. The US has made it clear that NATO allies failing to meet the 2% defence spending threshold cannot expect American protection, casting doubt on the applicability of Article 5 of the Washington Treaty to certain members. This policy shift not only shakes NATO and the EU but also signals a shift in US military engagement in Europe. Washington will now decide where to plan and exercise based on defence budgets, potentially reducing or repositioning its presence on the continent (Kube, Lee, & Tskirkin, 2025).
