The article discusses how U.S. President Donald Trump's aggressive stance, including threats to annex Greenland, has shattered the illusions of his European supporters from the far-right populist movement. Prominent figures such as Nigel Farage in the UK and Matteo Salvini in Italy had long considered themselves to be allies of Trump in their fight against liberal internationalism, only to face the stark reality that Trump's demands may undermine not just their political standing but also the sovereignty of their nations.

Furthermore, the article highlights that these European leaders have made significant errors in their calculations regarding Trump's intentions and character. In their attempts to flatter and align with Trump, leaders have shown a willingness to cooperate and compromise, failing to recognize that Trump’s methodology is rooted in the exertion of power rather than partnership. The realization that Trump does not seek collaborative relationships, but instead aims for dominance, marks a crucial turning point for those who mistakenly viewed him as an ally.

In conclusion, the implications of this shift could be profound for European politics as leaders wrestle with the consequences of aligning themselves with a figure like Trump, whose ambitions extend beyond mere political alliance to the potential undermining of national sovereignty. The uncertainty surrounding Trump's policies and intentions leaves European populists in a vulnerable position, forcing them to reassess their political strategies and alliances in a shifting landscape.
