In Russia it was called the Polish disease. In Poland it was the German disease; in Germany, the French disease; and in France, the Italian disease. The Italians blamed back, calling it the French disease. The instinct to find a scapegoat is so core to human nature that it’s hard to imagine the Swedish people calling the open sores the Swedish disease, or the Russians calling it the Russian disease. That’s not how people work. We need someone to blame and if a single foreigner came here with the disease, then we would happily blame a whole country. No further investigation needed.
