As tensions with U.S. President Donald J. Trump escalated in recent months, the Danish Armed Forces reportedly prepared contingency plans to destroy key airfields in Greenland in the event of a potential U.S. invasion. According to two European officials speaking to the Danish Broadcasting Corporation, troops deployed to the region were supplied with blood reserves and explosives intended to disable runways in Nuuk, the capital, and in Kangerlussuaq, a remote town within the Arctic Circle.
