What persuasive technique is being used in this passage from Wiesel's "Indifference" speech?

What about the children? Oh, we see them on television, we read about them in the papers, and we do so with a broken heart. Their fate is always the most tragic, inevitably. When adults wage war, children perish. We see their faces, their eyes Do we hear their pleas? Do we feel their pain, their agony? Every minute one of them dies of disease, violence, famine.
Some of them - so many of them -- could be saved.
