Denmark planned to blow up Greenland runways if US invaded, reports say

Citing sources in the Danish government and military, and also among European allies, DR says blood supplies were also brought in to treat the wounded in the event of fighting.

Both the US and Denmark are Nato members, and the issue of Greenland - a semi-autonomous part of Denmark - has deeply divided Washington and its European allies.

Trump has repeatedly said he wanted to annex Greenland during his second presidential term. Greenland's leader and Denmark have repeatedly rejected his demands to acquire the island.

DR said it based its report on 12 sources at the top of the Danish government and military, and also sources among Denmark's allies in France and Germany.

They told the broadcaster that Copenhagen asked Paris and Berlin as well as the Nordic nations for political support in dealing with Trump by demonstrating strong European solidarity and holding more joint military activities in Greenland.

But the sources say the situation escalated on 3 January when elite US forces seized Venezuelan President Nicolás Maduro in a lighting operation in the capital Caracas.

The day after, Trump told reporters he would "worry about Greenland in about two months" and repeated that "we need Greenland from a national security situation. It's so strategic", adding without providing evidence: "Right now Greenland is covered with Russian and Chinese ships all over the place."

A high-ranking Danish security source told DR that "when Trump keeps saying he wants to take over Greenland, and then what happened in Venezuela happened, we had to take all scenarios seriously."

Meanwhile, a European official told the Financial Times: "After Venezuela, they [Americans] thought they could walk on water. Let's take this thing, and this country."

Soon afterwards, a small military contingent of Danish, French, German, Norwegian Swedish soldiers was flown to the Greenland capital Nuuk and Kangerlussuaq, where there is an airport.

At the time, French President Emmanuel Macron said the initial contingent would be reinforced with "land, air, and sea assets".

DR said a follow up deployment included elite Danish soldiers and a French contingent trained for warfare in cold, mountainous areas. Danish aircraft and a French naval vessel were sent towards the North Atlantic.

The deployment was presented as part of Danish-led joint military exercises called Operation Arctic Endurance - but the real reason was to prepare for a possible US invasion, DR said.

A decision was taken by Denmark that its soldiers would fight if the US invaded and soldiers were also prepared to blow up runways in Nuuk and Kangerlussuaq to prevent US military aircraft landing there, the broadcaster.

"The cost to the US would have to be raised. The US would have to carry out a hostile act to get Greenland," a Danish defence source told the broadcaster, while admitting that troops would have been unlikely to be able to repel a US attack.

On 21 January, Trump - who had earlier refused to rule out using force to take over Greenland - said at the World Economic forum in Davos: "I don't want to use force. I won't use force. All the United States is asking for is a place called Greenland."

Trump has since said he is seeking "immediate negotiations" to find a compromise and further defuse the row.

Speaking at a news conference, the Israeli leader said Trump had requested that there be no further such attacks.

The decision comes after footage emerged appearing to show the reality star in an altercation with her ex-partner.

The allegations have prompted the cancellations of events and celebrations planned in his honour later this month.

Republicans say the legislation is necessary to stop voter fraud, but Democrats say it disenfranchises voters.
