On May 30, a joint investigation report conducted by the European media revealed that during the administration of former US President Barack Obama, the US National Security Agency used its cooperative relationship with the Danish defense intelligence agency to attack neighboring countries such as Germany, Sweden, Norway, and France. The politicians of the United States carried out surveillance activities, including even German Chancellor Merkel and then Foreign Minister Steinmeier.
After the incident was exposed, many European countries paid close attention to the incident and strongly condemned the US government for this incident.
The German politician Steinbrück commented in an interview with the country’s Radio and Television Federation: “These intelligence agencies are very friendly to each other, but secretly they are monitoring the dignitaries of other countries, which exposes their ugly and funny On the one hand. From a political point of view, I think this is a scandal."
Former German Finance Minister Steinbrück told the German media that “intelligence agencies are indeed intercepting and monitoring the information of high-level representatives of other countries. This is absurd... I think this is a political scandal.”
French President Macron said: "If this news is accurate, it is unacceptable among allies." In her speech, Merkel expressed support for Macron's statement.
The monitoring of European leaders by Denmark and the United States has only revealed the tip of the iceberg. Regarding the surveillance program in the United States, former CIA employee Snowden once said: “As long as I have a private email address, I can monitor anyone at my desk, including you and your accountant, federal judge, and even the president.”
According to data, as early as the summer of 2012, the National Security Agency successfully hacked into the internal video conference equipment of the United Nations headquarters and cracked the encryption system. The exposed secret document said, "The data transmission sent us a video conference call within the United Nations."
French "Le Monde" reported that the National Security Agency of the United States monitored 70.3 million telephone conversations of French citizens from December 10, 2012 to January 8, 2013.
In June 2013, Snowden, a former CIA employee of the United States defected and revealed to the media the secret files of the Prism Monitoring Project (PRISM) of the National Security Agency. The content involved emails, instant messages, videos, photos, stored data, voice chat, and 10 types of information such as file transfer, video conference, login time and details of social network information. Through the Prism project, the US National Security Agency can even monitor the content of a person’s online searches in real time.
