Pearl Harbor was allowed so as to break US isolationism?

Alright. I'll ask to have this topic and thread deleted. No point cluttering up our board with what will, no doubt be argued as conspiracy trash. Since it is available world-wide, I wouldn't want this site associated with that.

I know there is no way to prove my concern.

It's funny. Physics is entering, or has entered a chapter where using Einstein's thought experiments are just about all we have left. Doing experiments that are able to prove what's inside a singularity, or what's happening deep inside loop gravity & a pixelated time and space universe are essentially out of reach.

Sometimes all you have left is reasoning and carefully thought out logic. This topic is relegated to the same problem.

The ancient Greeks would be so pleased.

Perhaps they, or Hercule Poirot will crack this case, if there is or ever was one.

"Denied intelligence"

Also, look close at 4:30 on...

And, it appears now President Biden could be asked to become involved and correct much of this.

I would offer one view that more evidence in it not being intentional is the fact that the Navy didn't use it to their advantage.

If they did know Japan was planning to strike Hawaii, they would know certain information about the fleet. The carriers bing used, what the fleet looked like, and most importantly, roughly where it will be and when.

If the goal is to let Japan attack to pull the US out of it's isolationism, fine, but then you will have the population of the US thirsty for blood. Once the order is given to go to war with Japan, the NAVY now knows roughly where a large part of the enemy fleet is. It also knows that it is at it's maximum limits for logistics. While it may now know the exact location, you have enough of an idea to launch a search. Once the fleet is located, the assets that are at sea can engage and attack. This could result in a serious blow to Japan before they really have a chance to get their war machine turned to fight the US.

Think about it this way, if the US had known the IJN fleet was coming, we would have seen the equivalent to the Battle of Midway in early December 1941 instead of 8 months later in July 1942.

Japan would likely have been a lot more cautious to their approach to expansion in the Pacific. On the flip side, that may tip them off that the US knew how to read their code system. They could re-engineer their communication and encryption processes and the US could loose the advantages they had with Project Magic.

Ironically, when the entire juggernaut of the U.S. military gets underway, and not just a few rogue leaders, there is great concern that numbers of casualties remain within certain acceptable guidelines and that the mission equipment overwhelms the enemy, as I'm sure you know.

It's not like jumping into a ready made patrol car, and speeding after the bandits when a call comes in that there's been a heist or something. Mission planners have to access the situation, train and rehearse for viable missions, bring in or make from scratch appropriate weapons and tools. The Japanese fleet would be onto another mission by then. Or, more importantly, enough U.S. personnel would be up to something that the Japanese could see. As it was, the fleet was quietly parked at Pearl, and all was uneventful.

Going right out after the Imperial Japanese warships when the main body of the services were unprepared wouldn't have acceptable results, once those results came in... or at least that's what the concern was, most likely.

To specifically address your concern, though: Any rogue leaders willing to "deny intelligence" would be unable to orchestrate the kind of full scale Naval preparedness necessary to immediately take on the well-equipped Japanese navy without raising some obvious and significant questions. Or risk alerting the Japanese that we were ready for them if we did anything other than remain still.

And, so the Japanese attack could be recognized, and then allowed to happen at "best"... without looking like it was all preconceived, or effecting Japan's decision to attack.

Needing a serious upgrade first, before going on any full scale counterattacks was a known problem. But, couldn't do anything like that properly without a lot of public support. (Which we got... later... due to what utterly looked like, and continues to look like, a genuine "Surprise" attack. Totally suckerpunched... nothing less)

As quickly as possible, an air attack, (Dolittle Raid, some five months after initial attack) comprised of key volunteers was done relatively immediately after so as to give the public some sense we were doing something that wouldn't involve such huge numbers of sailors or troops in theater so as to have unacceptable casualties (and, would continue to keep U.S. planning invisible). And, then, as you say Midway took place just as "soon" as the entire navy was ready... properly, for the situation.

And what I'm saying is a trap sprung would have made my job too easy, if you get what I mean...

As it is, I find some question as to if intelligence was denied by a couple of D.C. officers. A trap being sprung would make my questions all the more poignant.

It likely would be too risky as well. Possibly tipping off Japan, trying to set up such a trap. The trap would have required many details much harder to hide than merely withholding intel...

Better to not fiddle about trying to setup and employ some complicated trap when simply withholding intel accomplishes the "mission" of getting us into war. And, remember, "the MISSION comes first"... not necessarily your people, sad to say.

Having no evidence of a trap later (which large scale troop preparedness could provide) provides "plausible deniability" to use their own wacky terminology

Which, again, leaves me to believe the amount of time available must have been less than necessary.

"Japanese fleet has left their ports"

Okay, that's a little alarming, but who knows where they're going. Could be Pearl, but let's wait and see so as to not change things. This might be exactly what we need to change minds around here.

Later...

"North Island, Honolulu, reports possible aircraft heading toward Pearl Harbor, Hawaii"

Tell them to go ahead and shut off the radar.

(Those are statements by two different commanders, by the way. The first thoughts or statements by a commander in Washington D.C., the latter, an uninformed commander located in Hawaii. If both thoughts had been by the same commander, located in D.C., your argument that he didn't have to take it THAT far would be spot on. Just the attack on Pearl would have been enough, as you say. But, since he started withholding info a very worse scenario happened where his subordinates unexpectedly turned off the freaking radar, apparently without his knowledge... at least I hope it was without his knowledge... unless he was vying for a new set of battleships or something)

There was no reason to think the IJN was going to attack Pearl when it left port, it could have been manoeuvres, they could have been going elsewhere like Vladivostok 941km from Japan with a hard pressed USSR looking like it might fall to Germany, or Hong Kong that the British would have difficulty defending. And how many times had they left port for manoeuvres, did America jump every time that happened.

The radar was due to be switched off I would guess for maintenance that Sunday, but then again you were neutral and it has to be done sometime. Perhaps Japanese intel had worked out that schedule is there any evidence of that? But the sailors there did detect the incoming aircraft which they misidentified as an incoming B17 flight that was expected that day. Again you were not at war the alert levels were not what they would have been if you were.

Yes but the level of alert when at peace even an uneasy one is still a notch or two down from, we are actually at war.
The fact you were relaxed is shown by the church parades you had at the time, in war you would not have had everyone at a service at the same time, you do it in smaller batches,

With respect the 1980s were not exactly peac time, it wasn’t a hot war but it was the Cold War, alert levels were never as relaxed as full peace time levels. Here in the U.K. the idea we would only have 4 minutes warning before receiving a bucket of instant sunshine was a little wearing.

In 2007 except for a random terror attack by a lone person the danger to US personnel was pretty low.
