What concerns truman about the events on the korean peninsula? check all that apply. communists’ use of subversive tactics the use of armed forces to spread communism the threat of a communist invasion of taiwan (formosa) north korea’s defiance of un orders the potential for instability in the pacific area

The correct answers are Communists' use of subversive tatics and The use of armed forces to spread communism.

During President Truman's admnistration, America was known for intervening whenever a communist outbreak surged. Communism was a major concern, given it threaten with the collapse of America's own political structure. Truman stood adamant with his tatics, even when his fellow citizens started to question his effort as the communists kept gaining victories on Eastern Europe and China.

The rest of the options were not a major concern to Harry Truman since:

relations between the soviet union and the united states were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. the distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the cuban missile crisis, brought them to the brink of war.

the united states government was initially hostile to the soviet leaders for taking russia out of world war i and was opposed to a state ideologically based on communism. although the united states embarked on a famine relief program in the soviet union in the early 1920s and american businessmen established commercial ties there during the period of the new economic policy (1921–29), the two countries did not establish diplomatic relations until 1933. by that time, the totalitarian nature of joseph stalin's regime presented an insurmountable obstacle to friendly relations with the west. although world war ii brought the two countries into alliance, based on the common aim of defeating nazi germany, the soviet union's aggressive, antidemocratic policy toward eastern europe had created tensions even before the war ended.

they united the colonies in their fight against the british.
