I gave someone I know some of the historic particulars about the technical particulars of the American JN decoding successes and how he intentionally provoked the Pearl attack knowing even which ships were being targeted, to the point he even gleefully predicted war entry days and weeks beforehand, and the person's best lame fallback was, "well, I guess that makes him a statesman."
Sure. Right as he was telling American parents, "I have said this before, but I shall say it again and again and again: Your boys are not going to be sent into any foreign wars."
First, bear in mind that with years of observation of how mechanisms of mass deceit work, I will not be impressed with anything like "most mainstream historians agree...," the more particularly as Ivy-degreed in the field myself and having observed failed historiography both in print and in realms like Wikipedia. Information control is in a few key respects both harder, yet much easier in our day than it was in the days of the USSR. I don't really have time to instruct you in everything or how you need to not categorically dismiss major stuff for minor detail, but if you're seriously interested in the truth, you can try http://www.jrbooksonline.com/fdr-scandal-page/pearl.html for a teaser look at one good start. Like I say, however, if all you do then is find source B that says, "Oh so and so's just a wingnut," you're not a real searcher and the discussion is functionally over. So we'll see.
