U.S. President Donald Trump¡¯s rationale for decapitating Venezuela¡¯s government is fueling concerns among European officials that they could soon face an existential dilemma over Greenland.

Trump over the weekend explained his decision to detain Venezuela¡¯s leader and have the U.S. run the country as a modern revival of the 19th-century Monroe Doctrine ¡ª the ¡°Donroe Doctrine,¡± as he dubbed it. The principle essentially claims a U.S. right to lead the entire Western Hemisphere, and to control any critical assets within it.

To Trump, that includes Greenland.
