Can you use Nazi in a sentence?

Here It Is:

"The leader of the Nazis, Adolf Hitler, killed millions of Jews in a horrible and unimaginable way, trying to get rid of every single one of them."

Nazi is just the short form of the name of a German nationalist party who happened to receive a leader named Adolf Hitler. It is no different in a sentence than saying, "Obama, a democrat, is the current President of the United States of America."
