The Strategic Defense Initiative (SDI) was a program to use laser technology to defend America against missiles. It was a research and development project initiated by President Ronald Reagan in 1983. The goal of the program was to develop advanced technologies, including lasers and missile interceptors, to create a defense shield against ballistic missile attacks. The initiative aimed to protect the United States and its allies from potential nuclear threats by intercepting and destroying incoming missiles before they reached their targets.
