Stepping out of an apartment complex into a warm Ohio night, Nashwaan Saddoon got into an old minivan and drove through Toledo to a hookah joint called Rocket Lounge. Sitting beside him was his friend, Amjad Arafeh. The two men had met only five months earlier, but they lived in the same building and already they were very close, despite their different backgrounds. Saddoon, an Iraqi Christian refugee, had been kidnapped and held hostage by Islamic State militants a few years before. Arafeh, a Syrian Muslim refugee, had escaped shelling and bombing in Damascus.
