Salah Hussein was 11 years old when he was woken up in the middle of the night by Israeli soldiers. It left him traumatized and terrified for years. It was triggering" to see any Israeli in uniform, he says. "For me, all of them were a threat." But decades later, Hussein, now a 33-year-old entrepreneur, has willingly and purposefully tied his fortune to his co-founder, who is an Israeli Jew. Hussein is one of about 35 entrepreneurs taking part in a start-up accelerator program called 50:50 Startups, where mixed teams of Palestinians, Israeli Arabs and Israeli Jews spend six months in a kind of business bootcamp. Program leaders take pains to say that 50:50 is not a political organization. That's what allows it to create an environment where each side can see the other as people, not enemies. In one stark example, a Palestinian man who grew up in a refugee camp near Hebron was sharing how he felt humiliated and harangued by IDF soldiers at checkpoints. Then he found out one of the Israelis he had come to know in the program was actually one of the soldiers stationed near his home. It was striking, he says, to hear that former Israeli soldier share how terrified he and others were of Palestinians. "They feel [the Palestinians] will attack them, or maybe shoot them, so they always stand by, [with] nerves tense," the Palestinian man said. "At the end of the day [the soldier is] a human being. He's someone like me who just wants to get back home safe and have dinner with [his] family."
