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

The depressing tale of the St. Louis is a case in point. Sixty years ago, its human cargo - nearly 1,000 Jews - was turned back to Nazi Germany. And that happened after the Kristallnacht, after the first state sponsored pogrom, with hundreds of Jewish shops destroyed, synagogues burned, thousands of people put in concentration camps. And that ship, which was already in the shores of the United States, was sent back. I don't understand. Roosevelt was a good man, with a heart. He understood those who needed help.
