“We have many, many people below the poverty line, and the infrastructure in Greenland is lagging, and our resources are primarily taken out without good profit to Greenland but mostly profit to Danish companies,” said Kuno Fencker, a pro-independence Greenlandic opposition MP. 

An attractive offer from Denmark and the EU could be enough to keep Greenlanders out of America’s grasp.

Option 3: Retaliate economically

Since Trump’s first term in office, “there’s been a lot of effort to try and think through how we ensure European security, Nordic security, Arctic security, without the U.S. actively involved,” said Thomas Crosbie, a U.S. military expert at the Royal Danish Defense College, which provides training and education for the Danish defense force.

“That’s hard, but it’s possible. But I don’t know if anyone has seriously contemplated ensuring European security against America. It’s just crazy,” Crosbie said.

The EU does have one strong political tool at its disposal, which it could use to deter Trump: the Anti-Coercion Instrument, the “trade bazooka” created after the first Trump administration, which allows the EU to retaliate against trade discrimination.

The EU threatened to deploy it after Trump slapped tariffs on the bloc but shelved it in July after the two sides reached a deal.
