Reagan announced Strategic Defense Initiative (SDI), An unexpected endorsement came from British Prime Minister Margaret Thatcher

On a pivotal day in history, President Ronald Reagan addressed the nation from the Oval Office, unveiling an ambitious proposal termed the Strategic Defense Initiative (SDI). This initiative aimed to develop a sophisticated missile defense system employing ground-based and space-based systems to protect the United States from potential nuclear attacks. The intent was to render nuclear weapons obsolete by intercepting and neutralizing them before they could reach their targets. This announcement marked a shift in U.S. defense policy during the Cold War, moving from mutually assured destruction to a strategy that emphasized defensive capabilities. The backdrop was an intensifying arms race between the United States and the Soviet Union. During this period, both superpowers had amassed substantial nuclear arsenals, posing a significant threat to global security. Reagan's SDI was seen as a technological leap, leveraging advancements in laser technology and space technology to achieve unprecedented defensive measures. However, it also raised concerns and skepticism about feasibility, cost, and the potential to exacerbate tensions between the two nuclear giants. The proposal received mixed reactions on the global stage. Critics argued that it would escalate the arms race and strain U.S.-Soviet relations further. Proponents believed it would provide a security shield, effectively deterring any nuclear aggression. An unexpected endorsement came from British Prime Minister Margaret Thatcher, a key ally of the United States. Thatcher's support underscored the special relationship between the United States and the United Kingdom, emphasizing the shared commitment to global security and defense collaboration.
