What was a significant military strategy proposed by Reagan regarding missile defense?

The significant military strategy proposed by Reagan regarding missile defense focused on the destruction of intermediate-range missiles, specifically through the Strategic Defense Initiative (SDI). Announced in 1983, SDI aimed to create a space-based system to protect the United States from nuclear missile attacks, particularly those from the Soviet Union. By targeting intermediate-range nuclear forces (INF), Reagan sought to strengthen U.S. defense capabilities and reduce the threat posed by these weapons during the Cold War. This approach ultimately led to renewed arms control discussions and was a crucial element in the latter years of the Cold War, contributing to the eventual signing of the INF Treaty in 1987, which eliminated an entire category of nuclear weapons.
