We must consider first that "A Modest Proposal" is in fact a satire. Swift's proposal to solving the economic problems of Ireland is to sell poor children as food to rich people. And in the excerpt, he exposes the idea of women as nothing but breeders. When the obvious though of possible protests to that degrading situation, he then says that such behavior is "<em>indeed very unjustly" </em>complained about. That contrast between something so horrific and such a simple answer as if there was nothing wrong with it is what shows clearly the irony of the text.
The repetition of the word "neutral" throughout the things on how we entered the World War I emphasizes the position of the United States in its attempt to be in the middle from the war.
