Auschwitz is the largest Jewish cemetery in the world. Auschwitz is where the systematic annihilation of European Jewry was refined and perfected. It is where four gas chambers and four crematoria annihilated more than a million Jews. It is the place where the notorious SS "Doctor" Josef Mengele conducted cruel medical experiments on people. It is also the place where thousands upon thousands of Poles, Roma and Sinti and Soviet prisoners of war were brutally murdered alongside the Jewish victims. We owe it to all of them, and to the survivors, to make sure that today's anti-Semites and hatemongers – those who want to destroy the Jewish people and its only refugee, the Jewish nation state Israel – will not get another go at it.
