Why did pres. truman believe that political change would come to the soviet union? a. the failures of the soviet nuclear programb. the appeal of freedom and the containment of communismc. the successes of the u. s. nuclear programd. the superiority of the u. s. space program

The correct answer is B. The appeal of freedom of the containment of communism. Both space programs were successful, just like their nuclear programs. One could even say that the Soviet space program was more successful considering they were both the first in space, and the first to have a space walk, while the US only landed on the moon first.
