Seventy-four years ago, the gates of the Auschwitz death camp were torn down, and the Nazis could no longer hide their heinous crimes. For decades, however, some have chosen not to see what really happened wherever the Nazis and their henchmen wielded power. Instead, they deny the horrors of a diabolical plan to implement a hateful idea of racial purity that ultimately led to the murder of millions of innocent men, women and children — including six million Jews.

But denying this history has only helped those who continue to perpetrate hateful ideas of racial, ethnic or religious purity, such as the genocidal killers of the Rohingya people in Myanmar, which is also known as Burma. The lessons of Holocaust are universal and Muslims around the world have a responsibility to learn them, heed the warnings and join the international commitment to ensure “never again.”
