Recent reports indicate that European leaders are on high alert for a potential deterioration in relations with the United States, following President Donald Trump's comments that framed Ukrainian President Volodymyr Zelensky as a barrier to peace negotiations. This statement has raised concerns in Europe about the possibility of renewed tension between the transatlantic allies, especially as they reminisce on previous conflicts such as Trump's suggestion to purchase Greenland from Denmark. The European response, characterized by unity and firmness, has proven effective in past situations, and is once again emphasized by statements from EU foreign policy chief Kaja Kallas regarding the necessity of strength and unity when dealing with authoritarian leaders, indirectly referencing Trump.
