متى قامت الولايات المتحدة  بإنشاء الدرع الصاروخي الأمريكي؟
On 23 March 1983, President Ronald Reagan announced a new national missile defense program formally called the Strategic Defense Initiative but soon nicknamed "Star Wars" by detractors. President Reagan's stated goal was not just to protect the U.S. and its allies, but to also provide the completed system to the USSR, thus ending the threat of nuclear war for all parties. SDI was technically very ambitious and economically very expensive. It would have included many space-based laser battle stations and nuclear-pumped X-ray laser satellites designed to intercept hostile ICBMs in space, along with very sophisticated command and control systems. Unlike the previous Sentinel program, the goal was to totally defend against a robust, all out nuclear attack by the USSR.
