On Wednesday, as Holocaust Remembrance Day begins, the world will bear witness to the stories of “The Children of October 7.” As a performer, I’ve always tried to use my platform to spread light. But after the evil of Oct. 7, when Hamas terrorists slaughtered more than 1,200 innocent people in Israel and kidnapped over 250 others — even babies — this granddaughter of Holocaust survivors couldn’t just keep dancing and singing. So I did what I knew I could do: I went to Israel to see everything for myself. I sat down with seven young survivors of the massacre — children who lived through horrors that no child should ever face — and I listened. And I promised them the world would hear their stories. This documentary, a collection of children’s testimonies, is not political. Rather, it’s a powerful message of resilience and bravery, as well as innocence — and, I truly believe, hope. I spoke to then-12-year-old Yael Idan, whose home was targeted by Hamas on Oct. 7. She and her family hid in their safe room — but the terrorists shot through the door. Their bullets hit Maayan, Yael’s sister, and Yael saw her die right before her eyes. Yael describes how the invaders used her mom’s cellphone to capture the carnage on a Facebook livestream for her friends, family and the entire world to see. She shares her grief at the loss of her father Tsahi, who was abducted to Gaza. His captors released proof of life for him, but he was eventually murdered there, his body finally released in the last hostage deal. Eitan Yahalomi, 13, was kidnapped with his entire family on Oct. 7. Terrorists separated him from his mother and sister — only later did he learn that they managed to escape. Eitan was taken alone into Gaza. He talks about how he was held in isolation for most of his 52 days in captivity. His father Ohad, who was shot while attempting to protect the family, was taken hostage and then killed by Hamas. His body came home to Israel in February. Yael, Eitan and the others who speak in the film didn’t ask for any of this horror. They want to play with their friends, go to school, live their lives. Now they wake up with nightmares. Some can’t sleep at all. They lost their families. They lost their childhood. I made this film to give the children of Oct. 7 a voice. And more than that: To give them space to grieve, to be heard and to show the world the truth of what they lived through. Their testimony hit close to the bone for me, because I grew up hearing stories of the Holocaust from my grandparents. My grandmother was only 13, Eitan’s age, when she was taken to Auschwitz. She watched as her own mother was beaten nearly to death before being dragged to the gas chambers. My grandmother lived. Her family did not. I always believed that the world had learned from that history. That something like the Holocaust could never happen again. But on Oct. 7, Jewish families were once again hunted. Babies were murdered. Women were raped. Children were taken hostage. And now, a year and a half later, people are questioning whether it even happened. They’re blaming the victims. They’re justifying the terror. Young viewers need to hear the truth. Too many of our kids are getting their news from TikTok — where antisemitism is rising faster than most realize. I know, because I’ve experienced it firsthand. I’ve seen my content removed, simply because it expresses the truth about the continuing assaults on Israel. I see Hamas propaganda going viral. I receive death threats daily. The parallels between my grandmother’s experience and those of these children of Oct. 7 are hauntingly similar. That’s why my documentary is premiering on Yom HaShoah, Holocaust Remembrance Day. This film is a wake-up call — a reminder of what can happen when we ignore evil. And I hope that young people will feel empathy, understanding and even outrage when they hear directly from their peers. You cannot look these kids in the eyes, hear their voices, and walk away unchanged. This film is also a call to action, inspiring viewers not just to speak out against antisemitism, but to stand up for truth, for humanity — and for the children who never should have had to bear these atrocities. Despite everything, the children of Oct. 7 still believe in hope. They still dream. They still laugh. They still want to grow up and make the world better. But first, they deserve justice. They deserve healing. Most of all, they deserve to be heard.
