The appearance of the "Star Wars" plan is the result of the intensification of the nuclear arms race between the United States and the Soviet Union. The United States believes that it is necessary to establish an effective anti-missile system to ensure the feasibility and reliable deterrence of its strategic nuclear forces and maintain its nuclear superiority. At the same time, the United States also wants to bring down the economy and politics of the Soviet Union through a protracted and costly space weapons race with its strong economic strength. In fact, the United States has also achieved its goal. According to the analysis, although the disintegration of the Soviet Union was not during Reagan's term of office, it was the "credit" of Reagan's "Star Wars". As former British Prime Minister Margaret Thatcher said, "He won the Cold War without firing a shot". Because the economic strength of the Soviet Union is not as good as that of the United States, it is impossible for the Soviet Union to invest heavily in unrestrained development as the United States, so it advocates prohibiting the militarization of space. In the years after the "Star Wars" plan came out, the issue of banning the militarization of space has been the main topic of previous US-Soviet summits and nuclear negotiations. The Soviet Union asked the United States to give up the "Star Wars" plan, and the United States used it as a "trump card" to pressure the Soviet Union to make concessions on land-based intercontinental missiles. The two sides are arguing endlessly about this. After the disintegration of the Soviet Union, Russia's negotiating position was greatly weakened. The United States and Russia finally reached the Treaty on Further Reduction and Limitation of Strategic Offensive Arms in 1993, which was beneficial to the United States. The United States achieved the expected goal, and the Clinton administration announced the end of the "Star Wars" program in May 1993. The declassified documents released by CIA 200 1 show that the "Star Wars" plan turned out to be a scam. 1983, Reagan put forward the "Star Wars" plan. After four years of investigation and study, the CIA organized a group of experts on the former Soviet Union in 1987, and released a forecast report according to the international situation at that time. This report is not only very timely, but also quite accurate in analysis. It is believed that the Soviet Union at that time was unable to deploy its own missile system to counter the air-based missile defense system of the United States, and the former Soviet Union was most likely to take diplomatic action or further strengthen arms control in exchange for concessions from the United States on the "Star Wars" plan. According to the report, "Star Wars" will put the Soviet Union in a dilemma. If they want to keep up with the US missile defense plan and spend billions of dollars on weapons every year, their industrial modernization plan will be postponed. If the Soviet economy fails, the domestic situation will be turbulent. Therefore, it is impossible for the Soviet Union to adopt a tit-for-tat policy towards the "Star Wars" plan. In other words, the Soviet Union will not make a large-scale missile plan to compete with "Star Wars", but only take a diplomatic offensive for national security. 1986 10 In Iceland, former Soviet President Gorbachev met with former US President Ronald Reagan, trying to persuade Reagan to give up the "Star Wars" plan by dismantling all ballistic missiles as bait. Reagan certainly disagreed. However, to what extent the Soviet Union was worried about the "Star Wars" plan, the CIA has been unclear. However, ten years later, Reagan's plot was exposed to the world. "Star Wars plan is just a scam. However, the Pentagon claimed that the "Star Wars" plan was not implemented because of technical defects.
