My grandmother’s Nazi killer evaded justice. Modern war criminals must not

As the 75th anniversary of the Nuremberg trials approaches, Ilse Cohn's grandson calls for international law to ensure those committing atrocities today face retribution

The man who ordered the murder of my grandmother never stood trial for the crime. Nor did he stand trial for any of the other 137,000 murders he ordered during five short months in 1941.

I know who he was. His name was Karl Jager, and he was the commander of a Nazi execution squad in Lithuania, where my 44-year-old grandmother had been deported from her home town in Germany. He is just one of several hundred thousand men and women who were never brought to justice for the part they played in the Nazi holocaust. It's estimated that up to a million people were directly or indirectly involved in holocaust atrocities, yet only a tiny fraction - perhaps no more than 1% - were ever prosecuted.
