Answer: In this case, both pronouns can be used to complete the sentence as both terms grammatically make sense, however whom is the prefered pronoun.
Explanation:
The difference between “who” and “whom” is the same as the difference between “I” and “me;” “he” and “him;” “she” and “her;” etc. Who, like other pronouns such as I he, and she, is a subject. So, it is the person performing the action of the verb. On the other hand, whom, acts like me, him, and her in a sentence. It is the object. Therefore, it is the person to/about/for whom the action is being done.
But what does that mean? “Who,” the subjective pronoun, is the doer of an action. For example, “That’s the girl who scored the goal.” It is the subject of “scored” because the girl was doing the scoring. Then, “whom,” as the objective pronoun, receives the action. For instance, “Whom do you like best?” It is the object of “like”.
Who should be used to refer to the subject of a sentence.
Whom should be used to refer to the object of a verb or preposition.
This is just my guess, but maybe it's because the dictators use their words to climb up and become one?
For example, Adolf Hitler was in the congress for a long time before he became a dictator. He talked and gave lots of speeches that the Germans (At the time) thought were good, so they slowly trusted him and unfortunately let him become dictator.
I wouldn't use this as an answer to a quiz or test, though.
