Khrushchev explains the Soviet Union's decision to resume nuclear testing, attributing it to ongoing threats from Western powers and the lack of genuine progress on disarmament. He criticizes the US, Britain, and France for continuing nuclear tests and accuses them of using peaceful testing as a cover to improve their weapons. Emphasizing that true security can only come through complete disarmament, Khrushchev defends Soviet actions as necessary for national defense while reaffirming the USSR's broader commitment to global peace and disarmament.
