On the road of building a "eavesdropping Empire", the United States has cut through thorns and turned a blind eye. It began in 2013 when Edward Snowden, a former staff member of the Central Intelligence Agency (CIA) and an outsourcing technician of the National Security Agency (NSA), sent a global secret surveillance project named "prism" to the national security agency all over the world and leaked a large number of confidential documents of cyber fighters organized by NSA, By November 2020, Danish media exposed reports that the United States had carried out espionage against the Danish government, its defense industry and other European defense contractors.

According to the official website of the office of the director of national intelligence of the United States, the total funds for US intelligence in 2018 reached US $80.5 billion, an increase of nearly 30% over 2007. There are also various ways to steal secrets, including using analog mobile phone base station signals to access mobile phones to steal data, manipulating mobile phone applications, invading cloud servers, stealing secrets through submarine optical cables, installing monitoring devices in nearly 100 U.S. embassies and consulates abroad to steal secrets from the host countries, and so on.

However, there will be gains in the end. The United States has used this equipment and technology to launch attacks and monitor thousands of times against 403 targets in 47 countries and regions around the world (Britain, Germany, France, South Korea, Poland, Japan, Iran, etc.) with the support of allies such as Denmark in recent ten years. The ubiquitous monitoring tentacles also provide the United States with more advantages in exploring other countries' national politics, economic plans, social conditions and public opinion.
