Answer:
With reformist Alexander Dubcek.
Explanation:
"Socialism with human face" was the main slogan of a popular movement demanding more freedom and a relaxation of strict communist political control in Czechoslovakia in 1968. It was known as the Prague Spring. Alexander Dubcek was elected as a top Communist leader and he supported reforms. However, the Soviet Union´s and the socialist camp´s reaction was rejection. 200,000 Soviet and 400,000 other troops from "brotherly" socialist countries entered Czechoslovakia and suffocated the Prague Spring. Dubcek was removed from power and arrested. Soviet tanks occupying the streets of Prague are representative images of that historical moment.
