Why is Holocaust Remembrance Day relevant to me?

The Holocaust was a defining event of the 20th century and is part of the world's history. Although the United States was not occupied during World War II, the impact on Americans was significant and wide-ranging:

• Refugees fled here from Nazi persecution
• Survivors and refugees who rebuilt their lives in
  the United States are part of our national heritage
• Our country was engaged in a war to defeat the
  attempt of the Nazis to occupy and oppress the
  European continent with its supremacist ideology
• U.S. troops liberated Dachau and Mauthausen
  concentration camps
• The United States played a lead role in developing the international conventions protecting universal human rights, after World War II,
  the world came to terms with the impact of Nazi policies. »
