Trade tensions between the United States and its major partners have resurfaced, reviving the specter of a new economic war. Washington has announced an increase in tariffs targeting Canada, Mexico, and China, a decision that marks the return of the protectionism favored by Donald Trump. This tariff offensive has immediately sparked reactions everywhere, particularly in Europe, where the European Commission is closely monitoring the situation. Although the European Union is not yet directly affected, Brussels fears an expansion of American measures and warns that it will not remain passive. The Commission has already expressed its strong disagreement with this policy and states that it is ready to adopt retaliatory measures to protect the continent's economic interests. In the face of this new trade offensive from the United States, the risk of escalation between the two blocs cannot be ruled out.
