Yesterday, President Donald Trump canceled a meeting with the new Danish prime minister, Mette Frederiksen, because she refuses to discuss the sale of Greenland. Greenland used to be a Danish colony but now belongs to the people of Greenland—the Danish government could not sell the island even if it wanted to. Trump likely did not know that Denmark is one of America’s most reliable allies. Danish troops, for example, fought alongside U.S. forces in Iraq and Afghanistan and suffered 50 fatalities, and Danish forces were among the earliest to join the fight against the Islamic State.

Many Americans may laugh off Trump’s latest outrage, but Trump crossed an important line. It is one thing to float a cockamamie idea that no one believes is serious or will go anywhere. “Let’s buy Greenland!” Yes, very funny. A good distraction from the economy, the failure to deal with white supremacy, White House staff problems, or whatever is the news of the day. It is quite another to use leverage and impose costs on Denmark in pursuit of that goal—and make no mistake, canceling a presidential visit is using leverage and imposing costs.
