Dr James H. Kitchens III, an archivist of the United States Air Force Historical Research Center, criticized Wyman for his neglect for the situation of total war in which the Allies were enveloped and for basing his book on sociopolitical sources, without quality references to military history, which he argues is crucial to the bombing debate. Kitchens argued that it would not have been practical to bomb Auschwitz. Kitchens' two principal points are 1) the Allies did not have sufficiently detailed intelligence about the location of these facilities to reasonably target them, and 2) the logistics of bombing would have been too difficult to reasonably expect a successful result. Historian Richard Levy supports Kitchens' position. Other historians have pointed out 1) there were opportunities for the Allies to acquire sufficient military intelligence on potential Auschwitz targets, though it appears that no concerted effort was made gather such information. and 2) there were many successful Allied bombing missions that were just as difficult and were supported by comparably incomplete intelligence. The notion that the Auschwitz mission would have been particularly difficult is strongly challenged; some have speculated that Kitchens may have been influenced by the desire to defend his employer.
