First off, there is no secret left to the method used to decode JN-25.

Yes, that is what I said previously.

So, nothing is being held back for reasons of "National Security."

Not true. The archives themselves are "security classified", as the link below states....

Records of the Office of the Chief of Naval Operations

Historical World War II and prior records from Naval Security Group Central Depository Crane Indiana 1919 - 78. Materials security classified. Contact the Archives II Military Records Staff, 301-837-3510.

So do these classified records actually include JN-25 related documents?

More than likely any unreleased messages were either never decoded, possibly lost, or maybe no-one ever asked for them.

Again untrue. Researchers, whether they support a conspiracy or not, admit these messages both exist and have been requested for release.

In his book "Too Late for Pearl Harbor", author Stephen Budiansky (an anti-conspiracist) writes...

"What has not been well established, because of continuing security classification of key documents, is just how much of JN-25 was readable in the critical months before the Pearl Harbor attack."

Even if we did have them I doubt that they would reveal anything about the Pearl Harbor attack we don't already know.

Well, it should be clear by now that we do have them. That you doubt they would reveal anything new is an entirely reasonable argument. But personal opinions, whether yours or mine, are certainly not valid reasons to withhold their release.

Turbonium is implying that there is some great secret hidden in these messages. Frankly, I'm doubtful. What proof do we have that they are being witheld so far besides his assertion?

Again, it should now be evident that we have them, beyond my "assertion".

As for my "implying..some great secret", I don't have proof that they do contain anything significant, but the continued refusal to release them leaves me with some doubt that they are completely without significance. In contrast, you doubt they would reveal important information unknown to the public. But as I said, our opinions are irrelevant to the release of the documents.

Anyway, the issue of the messages is irrelevant to the history of the Pearl Harbor attack. Even though these 25,000+ messages had been intercepted and sent to Hawaii and Washington there was no way to read them as JN-25 had not been broken before the attack

If it's irrelevant, then they should be released, and the whole issue of whether or not JN-25 was decoded by the US Government before Dec.7 will be resolved. And your position will be found correct.

Unless, of course, turbonium is subscribing the the CT that the nefarious folks in DC had actually already broken JN-25 and were witholding the info so the attack would succeed. Is that your thesis?

I'm skeptical about what was known prior to the attack. I don't "subscribe" to that view, if you mean I see it as being the irrefutable truth. I do "subscribe" to letting the truth be known - we can start with the release of these messages. You obviously would have no objections to that.

If so, it's most definitely not one any historian of the subject would take seriously.

I couldn't care in the least who does or doesn't take the issue seriously. The whole thing may end up being nothing more than a crazy, nonsensical theory. I would prefer that it did, in fact. Unless one is mentally unstable, nobody would actually prefer or be happier if the truth revealed their government was "nefarious" in it's actions.
