Communist leaders outside of Czechoslovakia were very alarmed about the Prague Spring because they also believed in the __________ theory.

Sagot :

The correct answer is "domino"- the domino theory says that if one country fell under a commonist regime - their neighbours would follow (that's what the west feared) and otherwise - if one country became capitalist, the rest would follow- what the east feared.

Communist leaders outside of Czechoslovakia were very alarmed about the Prague Spring because they also believed in the DOMINO theory.

The Domino Theory, or also called the snowball effect sequence, is a political theory that states that if a country enters a certain political system, it would drag others from its area towards that same ideology.

The Prague Spring was a period of political liberalization and mass protest in communist Czechoslovakia after the Second World War. It began on January 5, 1968, when the reformer Alexander Dubcek was elected First Secretary of the Communist Party of Czechoslovakia, and continued until August 21, 1968, when the Soviet Union and other members of the Warsaw Pact invaded the country to suppress the reforms and avoid protests in other communist countries.
