announcement of a new policy aimed at containing the spread of communism

answer:

use of the cia to bring about a change in government in those two countries

explanation:

in the 1950's, guatemala and iran took a turn in their politics and became pro-communist. this angered the united states, and in order to stop this process, and remove the communism from these two nations, cia was employed. cia was used in order to shake the governments by using propaganda, organizing protests, training and militarizing some of the population that was opposing that. this resulted in overthrows in the governments, organized by the united states, but the governments that were set in place by the united states didn't lasted long, so the effort was not really a long term success.
