Star Wars and Strategic Defense Initiative
In March 1983, Reagan introduced the Strategic
Defense Initiative, a defense project that would have used ground and space-based systems to protect the United States from attack by strategic nuclear ballistic missiles. Reagan believed that this defense shield could make nuclear war impossible but disbelief that the technology could ever work led opponents to dub SDI "Star Wars" and argue that the technological objective was unattainable. even though at the time it was unattainable it still led the Soviets to believe that it was possible and in a way tricked the Soviets into bankrupcy.
