Strategic Defense Initiative
The Strategic Defense Initiative (SDI) is a proposed missile defense program initiated by the U.S. government in the 1980s, aimed at developing advanced technologies to protect against nuclear missile attacks. While primarily focused on national defense, its relevance to UAP/UFO research stems from the exploration of advanced technologies and systems that could potentially intersect with aerial phenomena. The program has connections to military and intelligence communities, reflecting the government's interest in innovative defense strategies during the Cold War era.
