It’s very telling that Trump’s first inclination should he win the presidency is to take revenge on those who opposed him. That doesn’t bode well for a Trump West Wing filled with people who are afraid to tell him anything that he might disagree with.
You need to read Machiavelli’s The Prince.
From the Spark Notes:
Therefore, when a prince decides to seize a state, he must determine how much injury to inflict. He needs to strike all at once and then refrain from further atrocities. In this way, his subjects will eventually forget the violence and cruelty. Gradually, resentment will fade, and the people will come to appreciate the resulting benefits of the prince’s rule.
