Twilight Zone- The Mirror

Here's the wikipedia synopsis of a Twilight Zone episode that's interesting in terms of McCarthyism and Castro's resignation (the main character is supposed to look like Castro)

Synopsis
A Fidel Castro lookalike, played by Falk, celebrates the victory of the “people’s revolution”, led by himself and his four life-long confidantes. The ambitious Central American farmer faces down the overthrown leader, who warns him that he will soon see his enemies everywhere, including in an ornate mirror on the wall.
When the new leader begins to use methods much like his predecessor, his friends begin to argue with him over the course of the revolution. One by one, he believes he sees each of them try to betray him as he looks in the mirror. One by one, he has them executed, until finally he falls victim to his own paranoia. In the end, he indeed sees that the true enemy in the mirror is himself.
