Final answer:
The Soviet response to the uprisings in Hungary and Czechoslovakia shows their determination to maintain control and suppress democratic reform.
Step-by-step explanation:
The Soviet response to the 1956 uprisings in Hungary and the 1968 unrest in Czechoslovakia suggests that the Soviet Union was determined to maintain its control over Eastern European countries and suppress any attempts at democratic reform or independence. In both cases, Soviet forces were sent to crush the uprisings and reinstall Communist governments that would remain loyal to the Soviet Union.
