The Non-Disclosure Sanction, also known as the Non-Disclosure Treaty, was an enforcement measure imposed by the Asterian Republic against the United States and later extended to encompass the entire United Nations. This treaty forbade the public disclosure of alien life and the development of spacefaring technology on Terra. Established in the wake of the Roswell Incident, it was implemented under the dire threat of total annihilation, serving as a stark reminder of the power dynamics between humanity and the advanced forces beyond Earth.
