Trump's Greenland Remark Revives Obscure NATO Shoot-to-Kill Pact

A decades-old NATO agreement could force Danish and U.S. troops into a theoretical firefight, experts warn. The clause has gained new attention after former U.S. President Donald Trump repeated his interest in buying Greenland. The agreement is a Cold War relic. It states that if U.S. forces attack Denmark's territory, including Greenland, Danish troops are obligated to resist—with lethal force if necessary. This "defend first" rule is standard for sovereign nations within the NATO alliance. Trump's renewed comments about acquiring the autonomous Danish territory have triggered urgent discussions in European capitals. Officials are concerned the rhetoric could test the resilience of NATO treaties. While a direct military conflict is considered highly unlikely, the situation highlights rising tensions. European leaders are now publicly examining long-dormant protocols, fearing unpredictable diplomatic clashes.
