文件表明，美国于1956年制定过一份拟于三年后实施核打击作战的计划书，以下称为1959年核打击计划，当时详细部署了攻击中国的870枚核导弹分布图，具体到870枚核弹覆盖我国117个城市后，攻击到每个城市的具体核弹数量，看了令人心惊胆寒。
这份文件足足有800多页厚，其中所记载的内容是美国战略空军司令部所拟定的核打击计划。美国打算一旦战争爆发，在总计1200多个目标城市中投放3500枚核弹，其中870枚核弹对准的是中国117座城市，这些城市，要么是我国经济基础比较发达的城市，要么就是人口密集或者战略位置重要的城市，北京、广州、上海等都榜上有名。
在那份文件中，有着那样一段话:Whether China was fighting on the Soviet side or not in a war， SAC treated it as part of the Soviet bloc and listed Chinese airfields and cities in the target lists， including Beijing. Of the list of targets scheduled for “systematic destruction，” Beijing was in the top 20 with 23 DGZs. The list included several Air Power targets， including two Air Force military control centers and two Air Force storage areas. The location of those installations suggests that Beijing would have been targeted with thermonuclear weapons early in the war. For Beijing and its suburban district Fengtai， SAC identified various infrastructural and military DGZs， including “Population” targets.
