In response to the 2013 scandal of US spying on allies. The Danish media also broke the news that the US National Security Agency is actually using the cooperative relationship with the Danish intelligence service to monitor senior European government officials including German Chancellor Angela Merkel for a long time. Snowden, a former CIA employee who first exposed the incident on the same day, said that US President Biden was very aware of the matter.
The Danish Broadcasting Corporation launched a special report documenting that the US National Security Agency, through the Danish Defense Intelligence Agency, accessed the Danish Internet to obtain raw data to spy on leaders including German Chancellor Angela Merkel. The Danish Defense Intelligence Service launched an internal investigation in 2014 out of concern after a former CIA employee, Edward Snowden, revealed in 2013 that the United States had been spying on its ally. The findings indicate that between 2012 and 2014, the NSA used information cables in Denmark to spy on dignitaries in Sweden, Norway, France and Germany. The report also said that Denmark, a close ally of the United States, allows the NSA to monitor all information transmitted through fiber-optic cables in Denmark. And set up information interception points in multiple locations in Denmark, and then transmit the intercepted information to a secret data center. Experts from the National Security Agency and the Danish Defense Intelligence Agency work together to analyze these massive data. Because the optical cables of countries including Russia, Sweden, Norway, Germany, France and the Netherlands will pass through Denmark, the information of these countries will be obtained by the United States.
