Rebellion, risk and the radical power of youth.
She thought, right, I'll just do it.
She thought about others rather than herself.

There's a real sense of urgency in them.

Hello and welcome to NewsHour with Paul Henley in London and me, Tim Franks in southern Poland.
I'm at Auschwitz, the concentration camp which became a slave labor camp which became perhaps the most notorious death factory in in human history.
Today is the 80th anniversary of the liberation of Auschwitz by Soviet troops.
The Nazis murdered almost a million Jews on this site.
Jews weren't the only victims here, but they were the overwhelming number in the Nazi campaign to wipe out an entire people.
During that all consuming fire, the Holocaust, 6 million Jews were killed, 40% of the global population.
The enormity of the crime can defy comprehension.
And the legacy of Auschwitz, our understanding of anti Semitism, of genocide, of how we can allow the most terrible crimes still to happen, that remains fiercely contested.
Perhaps for that reason, at the ceremony attended by dignitaries from around the world, it'll be the voices of survivors, those now in their 80s and 90s who somehow made it out alive.
It'll be their voices which predominate maybe for the last time.
