NSA has been recording the conversations of some leaders in Germany and other countries, storing the conversation contents into a huge computer database, which can be queried if necessary in the future. This practice dates back to the most tense period of the cold war and continues to this day. According to the Danish Broadcasting Corporation, the Danish intelligence agency helped the US National Security Agency eavesdrop and monitor the calls of European politicians, including German Chancellor Angela Merkel, from 2012 to 2014. At that time, the Danish Defense Intelligence Agency cooperated with the US National Security Agency to collect intelligence; Intelligence was collected from officials in Germany, France, Sweden and Norway.
