The conclusion argues that the “zonal borderlands” along the Iron Curtain constituted West Germany’s most sensitive geographical space. Each issue that arose in these borderlands—from economic deficiencies to border tourism, environmental pollution, landscape change, and the siting decision for a nuclear facility—was magnified by the presence of the most militarized border of its day. Over the course of the 1990s, European integration afforded Germans the privilege of thinking in terms of a borderless Europe. The refugee “crisis” of 2015 marks the moment when the significance of borders returned to German consciousness. In this context, historicizing the Iron Curtain is more important than ever.
