Which of the following best describes the united state's policy of containment following world war ii

The United states of America's policy to check the spread of Communism best describes the united state's policy of containment following World War II.

Explanation:

First let us understand the 'domino effect'. A Domino effect is the collective effect produced when one event sets off similar types of events. Containment was a foreign policy of United states of America after the World war II (during the cold war).

It was laid out by "G.F. Kennan" in 1947. He stated that communism had to be contained or else it would spread to neighbouring countries. This theory of G.F. Kennan is called Domino theory. It later led "United states of America" to intervene in Vietnam as well as central America.

the berlin blockade was an international crisis that arose from an attempt by the soviet union, in 1948–49, to force the western allied powers (the united states, the united kingdom, and france) to abandon their post-world war ii jurisdictions in west berlin. in march 1948 the allied powers decided to unite their different occupation zones of germany into a single economic unit. in protest, the soviet representative withdrew from the allied control council. coincident with the introduction of a new deutsche mark in west berlin (as throughout west germany), which the soviets regarded as a violation of agreements with the allies, the soviet occupation forces in eastern germany began a blockade of all rail, road, and water communications between berlin and the west. on june 24 the soviets announced that the four-power administration of berlin had ceased and that the allies no longer had any rights there.
