Fallout from our surface explosions in the Soviet Union, its satellites, and China would decimate the populations in the Sino-Soviet bloc as well as in all the neutral nations bordering these countries—Finland, Sweden, Austria, and Afghanistan, for example—as well as Japan and Pakistan. Given prevailing wind patterns, the Finns would be virtually exterminated by the fallout from surface bursts on Soviet submarine pens near their borders. These fatalities from U.S. attacks, up to another hundred million, would occur without a single U.S. warhead landing on the territories of these countries outside the NATO and Warsaw Pacts.
Fallout fatalities inside our Western European NATO allies from U.S. attacks against the Warsaw Pact would depend on climate and weather conditions. As a general testifying before Congress put it, these could be up to a hundred million European allied deaths from our attacks, “depending on which way the wind blows.”
