Perhaps, this is notably the most highly protected information in the world. The nuclear facilities by themselves are a secret and only specific people know where they are located. The nuclear launch codes are the most secretive information of the U.S. government, such that only top officials in the U.S. department of defense have access to these codes. The amount of nuclear weapons and the type of nuclear weapon that USA possesses remain undisclosed to the public. The public will never get to know of the nuclear information.
