What was the Strategic Defense Initiative (SDI), proposed by President Reagan in 1983?

• A. A system to intercept incoming ballistic missiles
• B. A new offensive missile program
• C. A space-based weather monitoring system
• D. A global disarmament treaty framework

Answer: (A)

The main idea behind this item is defense: creating a shield that could stop ballistic missiles in flight. The Strategic Defense Initiative, announced by President Reagan in 1983, was a plan to develop technologies—space-based and ground-based systems—that would intercept and destroy incoming missiles before they could reach their targets. It was envisioned as a way to deter or defeat a nuclear attack, rather than to launch more missiles or monitor weather. It wasn’t a treaty framework, and it didn’t become a deployed system during that era due to technical challenges, costs, and arms-control considerations. The concept, sometimes called Star Wars, influenced later U.S. missile defense research and policy, even though the full system was never realized at that time.
