Denmark has confirmed that its military doctrine requires troops to “shoot first and ask questions later” if the country, including the territory of Greenland, is invaded under any circumstance, even by a fellow NATO ally. The rule dates back to 1952, when Denmark formalised its rules of engagement during a defining period of the Cold War. According to Danish military doctrine, soldiers under attack must immediately engage the enemy without waiting for higher orders or political authorisation, even if commanders are unaware that war has officially been declared.
This confirmation comes amid heightened controversy after US President Donald Trump revived his long-standing interest in Greenland, a vast, sparsely populated Arctic island and self-governing territory of the Kingdom of Denmark, and suggested that Washington might pursue control of the territory, including by military means.
Why Greenland Matters
Greenland is rich in strategic value: it lies between North America and Europe, controls key Arctic sea routes opening due to climate change, and is home to significant natural resources. It also hosts the US Air Force’s Thule base, a major node in North American and NATO missile defence systems.
Trump has repeatedly described Greenland as vital to US national security. In statements, he has said the United States needs control of the island and has refused to rule out force as an option, though top US officials have declined to explicitly confirm a military invasion plan.

Denmark’s Firm Response
Denmark’s government, including Prime Minister Mette Frederiksen and Greenland’s leaders, has sharply rejected any idea of selling or ceding control of Greenland. “Greenland is not for sale,” Danish and Greenlandic officials have stressed, underscoring respect for sovereignty and international law.
Despite being NATO allies, the standoff has put Denmark and other European partners on alert. Berlin and other capitals are reportedly in close consultation with Copenhagen about diplomatic and strategic responses to the unfolding situation.
A Rule Still In Force
When asked about the 1952 engagement rule, Denmark’s Defence Ministry told local media that “the order on precautionary measures for military defence in the event of attacks on the country and during war remains in force.”
In other words, if any foreign army, even a powerful ally like the United States, attempted to invade Denmark or Greenland, Danish troops would be authorised to fight back immediately.
