Allusion analysis: Ender's Game, Chapter 7

Read the following excerpt from Chapter 7 of Ender's Game (it's the opening dialogue scene), then answer the question below:

"Isn't it nice to know that Ender can do the impossible?"

"The player's deaths have always been sickening. I've always thought the Giant's Drink was the most perverted part of the whole mind game, but going for the eye like that--this is the one we want to put in command of our fleets?"

"What matters is that he won the game that couldn't be won."

"I suppose you'll move him now."

"We were waiting to see how he handled the thing with Bernard. He handled it perfectly."

"So as soon as he can cope with a situation, you move him to one he can't cope with. Doesn't he get any rest?"

"He'll have a month or two, maybe three, with his launch group. That's really quite a long time in a child's life."

"Does it ever seem to you that these boys aren't children? I look at what they do, the way they talk, and they don't seem like little kids."

"They're the most brilliant children in the world, each in his own way."

"But shouldn't they still act like children? They aren't normal. They act like--history. Napoleon and Wellington. Caesar and Brutus." [emphasis added]

"We're trying to save the world, not heal the wounded heart. You're too compassionate."

"General Levy has no pity for anyone. All the videos say so. But don't hurt this boy."

"Are you joking?"

"I mean, don't hurt him more than you have to."
