Faced with two existential threats - nuclear war and climate change - planners have responded by proposing sweeping reforms for city-regions, often deploying the newfound rationales to re-package earlier ideas about the good city'. This paper analyses how mid-twentieth-century planning discourses regarding Cold War urban dispersal in the USA might help us understand contemporary conversations about urban climate change adaptation. We apply Kingdon's Multiple Streams Analysis and his concept of policy entrepreneurs to show how planners frame problems and shape policy agendas. We propose a subtype of design-policy entrepreneurs' who use the spatial and visual tools of planning and design to advocate for preferred policies. By analysing the rhetoric and visual representations made by planners and designers from 1945 to 1965, we examine how they repurposed long-standing ideas about urban deconcentration into dispersal for defence' proposals. Such proposals for dispersing urban settlements into separated and self-contained' units received a dysfunctional partial acceptance: housing and transportation legislation embraced the dispersal part but resisted the complementary elements aimed at limiting damages from nuclear attack by concentrating development into distinct nodes. We conclude by asking how the perils of such partial policy-making success might play out on the terrain of climate change adaptation.
