President-elect Donald Trump has tossed expansionist rhetoric at U.S. allies and potential adversaries with arguments that the frontiers of American power need to be extended into Canada and the Danish territory of Greenland,

The European Union will not let other nations attack its sovereign borders, France's foreign minister said on Wednesday, responding to comments by U.S. President-elect Donald Trump on taking over Greenland.

European leaders expressed their confusion and pushed back Wednesday against President-elect Donald Trump's refusal to rule out using military force to take over Greenland.

French Foreign Minister Jean-Noël Barrot says the European Union (EU) will stand firm in its alliance in the face of repeated comments from President-elect Trump about the U.S. acquiring Greenland from Denmark.

When President-elect Donald Trump mused about buying Greenland from Denmark during his first administration, the Danish prime minister called the idea “absurd” and rebuffed him outright.

German Chancellor Olaf Scholz said Wednesday that the principle of inviolability of borders applies to every country, however powerful, and suggested that expansionist comments by President-elect Donald Trump are meeting with “incomprehension” among European leaders.

Denmark's prime minister said Thursday she had reached out to President-elect Donald Trump following his remarks about taking control of Greenland.

After Denmark, France and Germany have strongly condemned Donald Trump's controversial Greenland ambitions, with leaders from both countries declaring that the territory rightfully belongs to the European Union.

European leaders reacted to Trump's statement at a press conference on Tuesday that he would not rule out military action to take control of Greenland. He had earlier vowed to slap high tariffs on Denmark if it refused to cede its autonomous territory.
