One Friday in late summer, just as the Syrian refugee crisis was beginning to peak, a blue station wagon pulled up to the Kara Tepe refugee camp on the Greek island of Lesbos. The car’s side mirror was held on with masking tape and force of will. Big letters on the side said “Free Food For All” in English and Greek. A half-dozen sunburned, chain-smoking Greek leftists of all ages piled out, followed by two barrel-sized aluminum vats, several gas burners with propane tanks, two folding tables, forty bags of pasta, a box of spices, a dozen car-battery-sized cans of tomato paste and a couple of three-foot-long wooden paddles for stirring soup.
