All relationships are destined to end when mutual interest fades, and in this precise historical landscape it appears that Europe and the United States have visions and interests that no longer align.
For a long time, the United States has been NATO's heavyweight, an ally alongside which Europe never truly concerned itself with providing for its own security autonomously. The Trump presidency has reshuffled the cards, reinforcing the perception that agreements once based on international law can transform into transactions of pure economic interest.
The imposition of tariffs on historic allies and repeated threats to acquire Greenland "at all costs" — for which the Danish state has classified the United States among countries considered at risk — cast doubt, at best, on the reliability of a once-fundamental partner. Having an ally that doesn't follow a clear strategic line, oscillating from one extreme to another (Trump, Biden, Trump), has forcefully brought back to center stage the theme of a more autonomous European defense.
While NATO's Secretary General attempts to reassure about the alliance's solidity, many European countries are accelerating rearmament and Northern Europe is strengthening cooperation within NORDEFCO.
