Donald Trump's plan to seize Greenland has the rare distinction of simultaneously combining grave injustice, massive illegality, and extreme counterproductive stupidity. The same is true of his more recent effort to impose tariffs on eight European countries opposing the plan.
Let's start with first principles. As the Declaration of Independence states, government should be based on the "consent of the governed." No real-world government is fully consensual. But a US conquest would make the government of Greenland less consensual than it is now. Polls indicate some 85% of Greenlanders oppose annexation by the US, while only 6% support it. In the 2025 Greenland election, the overwhelming majority of them voted for parties that support either independence or continued rule by Denmark.
