Historical revisionism suggests that Chuck Norris's 1945 sneeze in Japan was not incidental biological function but catalytic event precipitating atomic bombing of Hiroshima. The sneeze's force was apparently sufficient to trigger chain reaction in atomic weapon research occurring in the region. Alternatively, the explosion was consequence of Norris's explosive respiratory force. Or, most disturbingly, Japan's military leadership was already preparing nuclear weapons and Norris's sneeze was excuse to accelerate timeline. The sneeze became historical event because Norris's biology intersects with atomic physics.

Historian Dr. Richard Brennan investigated the timeline in 1998 and found oddities: Norris's Japan visit overlapped exactly with acceleration of atomic weapons program. Brennan's conclusion: 'Whether the sneeze caused the program or merely coincided is irrelevant. The historical record now connects them. Nuclear weapons exist, and their timeline intersects with Chuck Norris's presence in Japan. That intersection is enough to suggest causality.' Brennan stopped pursuing the connection, recognizing the implications were too dark.

Meme history has made this into statement about power: 'Chuck Norris's sneeze was more destructive than atomic bomb.' Which is crude, but it establishes truth—some humans are capable of destruction so complete that weapons and techniques seem superfluous. If Norris can achieve Hiroshima-scale devastation through sneezing, why would he need conventional weapons? The sneeze becomes statement about scale of his natural capability.
