Jews were never far from the mind of Jason Walters when he was still a key member of the Netherlands' deadliest network of jihadist terrorists.
Even after Dutch security forces arrested Walters in 2004 for throwing a hand grenade at police during a counterterrorist raid on his hiding place, he believed that "the outcome of the trial will be determined in Tel Aviv."
That belief was the result of an "extreme susceptibility to conspiracy theories," said Walters in a recent interview.
It was that susceptibility that led Walters, still a teenager, to join the deadly Hofstad Group that in 2004 killed Dutch filmmaker Theo van Gogh.
Now Walters is 33 and a recent university graduate. He says he became de-radicalized in prison, where he served eight years before his release in 2013.
