What was the soviet response to the massive retaliation?

The Soviet response to the U.S. policy of massive retaliation, which threatened nuclear retaliation against any aggression, was to enhance their own nuclear capabilities and develop a strategy known as "mutual assured destruction" (MAD). They aimed to ensure that any nuclear conflict would be devastating for both sides, thereby deterring U.S. aggression. Additionally, the Soviet Union increased its conventional military forces and engaged in proxy conflicts to counter U.S. influence around the world. This arms race and strategic posturing intensified tensions during the Cold War.
