On this day, 32 years ago, May 13, 1993 (March 22, 1993, the lunar calendar), the United States announced the end of the "Star Wars era." "Star Wars" diagram shown by the U.S. government On May 13, 1993, U.S. Secretary of Defense Aspin announced that the "Star Wars era" had ended and that the United States had abandoned its plan to build an anti-missile defense system in space. On March 23, 1983, then-U.S. President Reagan delivered a televised speech to the nation, publicly proposing the strategic defense plan (namely the Star Wars plan) for the first time. In his speech, Reagan first showed four satellite photos and some charts, showing that the Soviet missile force "has greatly surpassed that of the United States." He emphasized that the United States must further develop and strengthen strategic offensive weapons. At the same time, it must speed up the development of superweapons in the space age and establish an effective strategic defense system so that Soviet strategic missiles can be intercepted and completely destroyed before they reach the United States. At the time, White House officials said that the plan was to directly launch lasers, microwaves, particle beams, projectile beams, etc. from satellites to destroy Soviet missiles before Soviet nuclear missiles attacked U.S. territory. White House officials said the plan would require a significant increase in anti-missile science and technology research, with a planned funding of US$1 billion a year. And the plan will not be completed within this century and is expected to cost US$8000 to US$1 trillion. Many senior administration officials said Reagan's plan did not threaten the Soviet Union, nor did it violate the anti-ballistic treaty signed by the two sides more than a decade ago, because the treaty did not prohibit the research and development of defense systems. When the "Star Wars" plan was launched, it aroused strong repercussions. Almost no country except Japan supported the plan, especially the Soviet Union, which expressed strong opposition. The Soviet Union's greater response was to immediately develop anti-Star Wars methods and spend hundreds of billions of dollars on this in just a few years. However, what made the Soviets even more angry was that in the mid-1990s, the relevant U.S. authorities announced that the Star Wars program was a purely fictitious plan. The U.S. government had not studied the program at all and had not invested a penny from beginning to end. However, the Soviet Union invested too much in this century's lies, almost bankrupting the entire country. Essentially: The "Star Wars" program was the biggest conspiracy of the Cold War, and it eventually turned into a cruel joke and the best explanation for the crazy arms race of this century.
