The production of Tsar Bomba therefore became necessary because of foreign policy and propaganda considerations, to respond to US nuclear blackmail. As an expression of the concept of nuclear deterrence adopted during the leadership of Georgy Malenkov and Nikita Khrushchev, the actual strategic situation in consideration to this concept, for the Soviet Union, as a consequence of the disequilibrium with regards to the Soviet Union "vis-à-vis" America's nuclear weapons possessions, to the favour of the latter, was that the creation of Tsar Bomba represented a necessitated bluff.
