Explanation:

Passive voice is a form or set of forms of verbs in which the subject undergoes the action of the object.

Passive voice is used, when;

1: We don't exactly know the subject of the action e.g. A snake was killed. (We don't know, who killed the snake), the trees were cut (who cut them, no idea)

OR

2: When the action itself is more important (want to emphasize action) than subject of the action. For example, A snake was killed by him ( snake being killed is more important or emphasized than who killed the snake).

An easy and short-cut way to identify whether the sentence is a passive voice or not is;

Passive voice always have a form of be (be/is/are/am/was/were) which are followed by third form (past participle) of principal verb. If it is not so, the sentence is certainly not a passive voice. And if it does have this structure the sentence is certainly passive voice.

the speech this question is referring to is president kennedy's special message to the congress on urgent national needs, may 25, 1961

kennedy responds in a very direct and concrete way to those thinking that communism is a positive system:

"yet their aggression is more often concealed than open. they have fired no missiles; and their troops are seldom seen. they send arms, agitators, aid, technicians and propaganda to every troubled area. but where fighting is required, it is usually done by others--by guerrillas striking at night, by assassins striking alone--assassins who have taken the lives of four thousand civil officers in the last twelve months in vietnam alone--by subversives and saboteurs and insurrectionists, who in some cases control whole areas inside of independent nations." (kennedy)

president kennedy presents communism as cowardly, as a hidden and treacherous weapon that strikes from the shadows like thieves, he represents the system as not even being capable of showing and open and overt attack or confrontation. to finish up the response, he expresses that the system attacks even a country's idependence and freedom.
