Dating back to World War II, Nazi Germany wanted to use drugs and radio waves to create soldiers who were not afraid of death. [1][2] The United States, Russia and other countries have begun to develop brain weapons as early as the 1950s. The CIA called it Project MKULTRA. The United States also used brain-controlled weapons in the war against Iraq from 2003 to 2010. [3][4][5] Due to the immature technology and difficulty in conviction and arrest, victims of Russian brain-controlled weapons once wrote an open letter to the United Nations Commission on Human Rights. According to the St. Petersburg Times, the letter was signed by a large number of victims at the end, most of whom live in Moscow, St. Petersburg, and from Sevastopol, Ukraine. [6] In the past, scientists have used chips implanted in the brain to electrically stimulate the brains of animals, thereby inducing certain behaviors or emotions in these animals [7]. However, if these technologies are used in humans, they will be very harmful to health. .
