Copenhagen was so shaken that it sent blood supplies in readiness for battle, according to Danish media

Denmark reportedly readied itself for potential attack from the US in January – flying bags of blood to Greenland and explosives to blow up runways in case of battle with its former closest ally.

During the tense days when Donald Trump threatened to take over Greenland, a largely autonomous territory that is part of the Danish commonwealth, “the hard way”, Copenhagen was so shaken that it started preparing for US invasion, according to Danish public broadcaster DR.

When, in January, Danish soldiers were flown to Greenland, they were reportedly carrying explosives to destroy runways in the capital, Nuuk, and in Kangerlussuaq, a small town north of the capital, to prevent US aircraft from landing in the event of an invasion.

They also carried supplies from Danish blood banks to treat wounded people in the event of battle, according to DR, which had spoken to sources from across the Danish government, authorities and intelligence services in Denmark, France and Germany.
