Intelligence tensions rock NATO as Danish government issues espionage advisory

INTELLIGENCE PARTNERS IN THE North Atlantic Treaty Organization (NATO) are “not talking openly” anymore, while authorities in Denmark have advised government officials to disable Bluetooth functions on their devices due to spying concerns. According to reports in British news outlets, intelligence-sharing functions inside NATO are at a breaking point following a series of actions by the United States that one source described as “alliance-breaking moves” that could “thoroughly alter the global order for decades to come”.

One British outlet cited an unnamed “senior NATO insider” who said that the current dispute between the US and Europe over Greenland is “creating tensions and distrust between European and US colleagues in NATO”. The source added that European and Canadian NATO staff are “not talking openly” with their US counterparts amid “growing concerns that information will make its way back to [US President Donald] Trump”.

At the same time, reports from the US suggest that the White House has ordered the Pentagon to “scale back” its participation from NATO’s force structure and a number of transnational advisory groups. European and Canadian military officials are reportedly interpreting these moves as “the latest sign of the Trump administration’s drive to scale back the US military presence in Europe”.

Meanwhile, the Danish government has issued multiple advisories to its military and civilian officials to disable all Bluetooth functions across both government-supplied and personal electronic devices, reportedly over concerns of intensified foreign surveillance targeting Denmark. The Danish Defense Intelligence Service (DDIS) issued an advisory to military personnel across Denmark and Greenland to deactivate all Bluetooth functions.

The Information Technology Department of the Danish National Police issued a similar advisory to its personnel, instructing them to keep all Bluetooth functions deactivated until further notice. The advisory warned that wireless accessories, including Bluetooth-reliant headsets from popular brands like Apple could function as potential entry points for eavesdropping and other forms of data interception by foreign powers.
