Ok so to what extent did Hitler hear about submarine cooperation with the Japanese? What conversations did he have to approve sharing the Me-262 and Me-163 projects with Japan? What did he say after Midway, Guadalcanal and the Philippines?
You've got great questions exhausted, unfortunately I don't have the answers, and I think you would be hard pressed to find solid info that is not theory or opinion in regards to the Me-262 and Me-163 project. As for the battles you listed, like I mentioned earlier the Germans especially in 42 and 43 were focused almost entirely on the Eastern front, along with of course the failing situation in Africa by 1943. It is hard for me to believe that Hitler would even want to know how the war in the pacific was going after 1942.
But even without Hitler's declaration of war the US is still at war after PH. PH definitely changed the game, did did Hitler's declaration of war do the same? Perhaps so but my gut feeling is not anywhere near the extent that the attack on PH did. Especially when you consider the fact that the US would likely be in the war some time in the next 6 months anyway.
Bit of a closed loop there. But anyway, the ABC-1 talks established the "Germany First" policy, the Atlantic Conference confirmed that policy. So as soon as we were at war with Japan we went under the assumption that we would be at war with Germany hayaku.
Which again brings to question just how much difference Hitler's declaration made. If he really wants to throw a wild card out a declaration of war on Japan in support of the US would at least create some confusion.
OH I agree. Not sure it helps at all either. Would cause considerable confusion for a short period though.
Thank you. I can see the obvious reasons why Hitler was preoccupied with his failing offensives. However, I am not convinced (likely not even convincible!) that no German close to him not only had information of the Pacific War, but also briefed somebody else about it. You seem to understand my question just fine. But for those who don't, I would like to know WHO among Hitler's circle got this information. Do we have a list of Hitler's aids and their areas of responsibility? Can we deduce from this? Personally, this is WAY above my skill level. Who are the pros around here?
Absolutely there was someone in Berlin who received information from the Pacific, but Hitler had priorities in the way of intelligence, and unless it seemed to be of great importance he would probably ignore the basic info. I am no expert in Hitlers staff, and I wish I could pass along a name who can help you, but I can't think of anyone who knows of Hitlers direct staff. Heinrich Himmler or Freidrich Alper are the only ones who come to mind for me, chances are that one of the two notified Hitler of the attack on Pearl Harbor, and just about every other major happening Axis or Allied in nature.

JJWilson and R Leonard, Wow! Thanks for the insights. And to think I had given up on this thread as dead since July.
I'd also recommend poking around at hyperwar. There might be something in the intel intercepts for instance.
