In his inaugural speech, Trump did not mention Europe and hinted at imposing tariffs on countries selling products to the U.S., many of which belong to the European Union.
Trump showed his protectionism again, which would mainly affect Germany and Italy - the two largest European exporters.
Trump's imperialism and Elon Musk's interference in Europe have caused confusion, whilst the EU has responded diplomatically.
To counter potential tariffs, Von der Leyen, President of the European Commission, proposes more European integration and the pursuit of new markets, including China.
European countries must also deal with industrial weakness, high energy costs, fiscal imbalances and internal political crises.
A possible disengagement of the United States from NATO would require European states to increase their defense spending and seek other forms of financing.
The new focus of the relationship between the US and Europe will center on technology, trade, and defense.
Europe still depends heavily on the United States, which limits its room for maneuver.
Conclusion: Europe is facing a series of challenges that require a reassessment of its relations with the U.S., and also represent an opportunity to strengthen its strategic autonomy and security.
