Historians such as Herbert Bix, Akira Fujiwara, Peter Wetzler, and Akira Yamada assert that the post-war view focusing on imperial conferences misses the importance of numerous "behind the chrysanthemum curtain" meetings where the real decisions were made between the Emperor, his chiefs of staff, and the cabinet. Historians such as Fujiwara and Wetzler, based on the primary sources and the monumental work of Shirō Hara, have produced evidence suggesting that the Emperor worked through intermediaries to exercise a great deal of control over the military and was neither bellicose nor a pacifist but an opportunist who governed in a pluralistic decision-making process. American historian Herbert P. Bix argues that Emperor Hirohito might have been the prime mover of most of the events of the two wars.
