Whitehead concludes that ultimately Hirohito was "powerless" and comparisons with Hitler are "ridiculously wide off the mark." If Hirohito acted too insistently with his views he could have been isolated or replaced with a more pliant member of the royal family. The pre-war Meiji Constitution defined the emperor as "sacred" and all-powerful, but according to Whitehead, Hirohito's power was limited by ministers and the military. Whitehead explained after World War II that Hirohito's humility was fundamental for the Japanese people to accept the new 1947 constitution and allied occupation.
