As it turns out, the original 1980s report vastly overestimated the amount of combustible fuel in cities and inaccurately estimated both modern nuclear weapon yield and blast size. Nuclear war would &lt;i&gt;not&lt;/i&gt; create firestorms capable of injecting soot into the stratosphere and would &lt;i&gt;not&lt;/i&gt; cause years-long crop failures. Nuclear war is, in fact, quite survivable.&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;skeptoid.com&amp;#x2F;episodes&amp;#x2F;4244&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;skeptoid.com&amp;#x2F;episodes&amp;#x2F;4244&lt;/a&gt;&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.nature.com&amp;#x2F;articles&amp;#x2F;475037b&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.nature.com&amp;#x2F;articles&amp;#x2F;475037b&lt;/a&gt;&lt;p&gt;&lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.quora.com&amp;#x2F;How-many-nukes-would-it-take-to-cause-a-minor-nuclear-winter-What-about-a-moderate-one&amp;#x2F;answer&amp;#x2F;Allen-E-Hall-2&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.quora.com&amp;#x2F;How-many-nukes-would-it-take-to-cause-...&lt;/a&gt;</text></comment>

Simple jealousy doesn&amp;#x27;t explain the vehemence.&lt;p&gt;As for the politics of the issue, mutual assured destruction has been the working theory since Eisenhower. Those who think strategic nuclear war is winnable, as well as the SDI nutters, are threats to that stability.</text></comment>
