SDI

SDI, or Strategic Defense Initiative, was a proposed missile defense system announced by the U.S. in the 1980s. Its goal was to protect the country from incoming nuclear missiles by using advanced technology, like space-based lasers and interceptors. Essentially, SDI aimed to create a defensive shield that could detect and destroy missiles before they reached their targets. While ambitious, it faced technical challenges and was never fully implemented. The initiative represented a significant effort to enhance national security through innovative technology, influencing the development of missile defense systems still in use today.
