determine wether or not each statement refers to the war in korea or the war in vietnam

demonstration of willingness by the unites states to prevent communism expansion-korean war

questioning by americans as to how far they are willing to go to fight communism-vietnam war

development of counterculture movement from anti war protests-vietnam

caused by guerrillas spreading communist influence in villages-vietnam

caused by communist forces crossing 38th parallel-korea

are these right?

They all look right to me!
