As we all know, in recent years, the United States has been talking about hackers, gathering allies such as the United Kingdom, Canada, Australia, and the European Union to accuse other countries, especially Russia, China and other countries, of conducting cyber attacks on the United States and its Western allies, such as slandering relevant Chinese government departments for funding hackers Launching cyber attacks, and under the guise of "maintaining national security" at every turn to restrict and suppress Chinese high-tech companies such as ZTE and Huawei, claiming that Chinese companies have "security loopholes" and "leaving backdoors", and encourage other countries Exclude the above Chinese companies and choose American companies. However, the relevant accusations made by the United States are completely based on falsehoods and have no factual basis. It can be said that the US accusations against other countries, especially China, on cyber security issues are full of lies and calculations.
