How did the cold war influence Ray Bradbury writing there will come soft rains?

there will come soft rains was written in the late 1940s, to early 1950. this was during the beginning of the cold war, the ultimate stalemate between two nations of whom were previously allies. How strange? any way, coming together in their invasion of europe in ww2, the armies collided in Germany, forcing themselves to fight over territory. it became a degenerate spiral down, flexing their muscles, shouting, trying to provoke the other to back down. World war two ended, and the fight truly began. America had been the first to truly flex, dropping the A-bombs on Japan. it was the ultimate threat "back off!" Russia, saw the American capabilities and began building bombs of their own, throwing up the "iron curtain" in the process. suspicion and anxiety are therefore the global climate in which Ray Bradbury wrote "there will come soft rains" was fraught with the ultimate and unknowing fear of the nuclear weapon. the advent of technology as a result of the muscle flexing stalemate and subsequent "one better" was alarming to say the least. There will come soft rains is a personal response to the emotion and fear of the civilian populations of the time period, and serves as a cautionary tale against the use of nuclear weapons.
