Ruesselsheim, Germany

With a population of just 67,656, Rüsselsheim is hardly the bustling metropolis many Americans dream of. The town's claim to fame is the Opel car factory, but beyond that, it's a sleepy commuter hub plagued by the bureaucratic headaches typical of German provincial cities. During World War II, Rüsselsheim residents even turned on American prisoners of war, killing six in a gruesome public attack. While the city has rebounded since then, a dark history and lingering resentments make it an unappealing choice for most Americans seeking a fresh start abroad.
