How did the arms race with the US affected the USSR?

The arms race with the U.S. significantly strained the USSR's economy and resources, as it necessitated heavy investment in military technology and nuclear arsenals. This competition diverted funds from vital domestic programs, contributing to economic stagnation and public discontent. Additionally, the constant pressure to match U.S. advancements heightened tensions and paranoia, impacting diplomatic relations and fostering an atmosphere of distrust both domestically and internationally. Ultimately, the unsustainable nature of this arms race played a role in the USSR's eventual collapse.
