Strategic defense initiatives

The Strategic Defense Initiative (SDI), proposed by U.S. President Ronald Reagan in 1983, aimed to protect the United States from nuclear missile attacks through a space-based defense system. The initiative sought to develop advanced technologies to intercept and destroy incoming missiles before they reached their targets. While it was intended to enhance national security during the Cold War, SDI faced criticism for its feasibility and high costs. Ultimately, the program evolved and many concepts from it contributed to later missile defense systems. It reflected the era's focus on preventing nuclear conflict through technological advancements.
