The Strategic Defense Initiative (SDI), commonly called Star Wars after one of the popular science fiction movies of the time, was proposed by U.S. President Ronald Reagan on March 23, 1983[1] to use ground-based and space-based systems to protect the United States from attack by strategic nuclear ballistic missiles. The initiative focused on strategic defense rather than the previous strategic offense doctrine of Mutual assured destruction (MAD).
Though it was never fully developed or deployed, the research and technologies of SDI paved the way for some anti-ballistic missile systems of today. The Strategic Defense Initiative Organization (SDIO) was set up in 1984 within the United States Department of Defense to the Strategic Defense Initiative. Under the administration of President Bill Clinton in 1993, its name was changed to the Ballistic Missile Defense Organization (BMDO) and its emphasis was shifted from national missile defense to theater missile defense; from global to regional coverage.
