A report released in 2013 by the Nobel Laureate International Physicians for the Prevention of Nuclear War and its U.S. affiliate Physicians for Social Responsibility demonstrated that a limited nuclear war involving just 100 Hiroshima-sized bombs—less than 0.5 percent of the world's nuclear arsenal—would be devastating. More than 20 million people would be dead in a week from the explosions, firestorms and immediate radiation effects. But the global consequences would be far worse. The climatic disruption and resulting decline in global food production would put two billion people at risk worldwide.
We could spend the equivalent of the entire U.S. defense budget (estimated to $590 billion annually) on a Nuclear Global Health Workforce and still not be adequately prepared for the consequences of even such a limited nuclear war. Our entire pattern of civilization, including the design of cities, human health resources and food production, would need to be changed to make it resilient to nuclear war. This has been repeatedly and conclusively determined by studies since the 1970s, including the "Medical Implications of Nuclear War" conducted in 1986 by the National Academy of Sciences and cited in Dallas's research.
Civilization as we know it cannot survive a nuclear war that involved the use of even a fraction of the world's nuclear arsenals on multiple cities. Yes, devoting more resources to preparing for a nuclear incident makes sense, but when it comes to nuclear war prevention is the only responsible course of action.
In order to fully succeed in that objective, nuclear weapons must be outlawed and permanently removed from national arsenals.
