What was the strategic defense initiative?

Strategic Defense Initiative (SDI), byname Star Wars, proposed U.S. strategic defensive system against potential nuclear attacks—as originally conceived, from the Soviet Union. The SDI was first proposed by President Ronald Reagan in a nationwide television address on March 23, 1983. Because parts of the defensive system that Reagan advocated would be based in space, the proposed system was dubbed “Star Wars,” after the space weaponry of a popular motion picture of the same name.
