Suggest you read the book At Dawn We Slept. It covers this myth quite comprehensively, and explodes it throroughly.
It was really completed by two of Prange's students [Donald Goldstein and Katerine V. Dillon] - Prange died in May 1980.
The appendix they added attempted to refute all revisionist claims and concluded with "in a thorough search of more than 30 years, including all publications released up to May 1, 1983, we have not discovered ..." Their claim was not quite true ... They never saw SRH-051, for example.
And as the years have passed more and more materials have been released ...
Stinnett's paperback is likely the most current in the US.
Timothy Wilford's Master Thesis (University of Ottawa) in History is noted in Stinnett's Afterword source notes ...
John Costello still "pulls" the Foreign Office chain ... gets ... " release is not in the national interest at this time."
I surmise that there is an explicit agreement between US/England/Austrialia/Canada/Dutch/ ... that the release of pre-Pearl Harbor materials be timed and coordinated together.
