Why did Soviet leader Nikita Khrushchev reject Eisenhower’s Open Skies proposal?

Soviet leader Nikita Khrushchev rejected President Dwight D. Eisenhower’s "Open Skies" proposal—which called for the mutual exchange of military blueprints and unhindered aerial reconnaissance—because he viewed the plan as a capitalist espionage device.12

Proposed at the 1955 Geneva Summit, the initiative was intended to address American fears of a surprise attack during the arms race by allowing both superpowers to monitor each other's military installations. While the proposal was well-received by international public opinion, the Soviet Union remained deeply suspicious of Western intelligence-gathering efforts, leading Khrushchev to denounce the plan and ultimately decline it.12
