I think I'd have problems with most of the lot. Speer, I might be able to enjoy talking to. Göring, what a pompous wind bag. I remember being at a party some years ago where there was a local moderately important politician present. The guy kept going around to all the guests and shaking hands saying "Hi I'm (whatever his name was) damn glad to meet you!" You knew he was a pretentious windbag when he did this the second or third time (lucky for me I found a bottle of single malt scotch....).
Räder, even as a navy man myself I likely would have had problems with. Everything I've read on him says he was a stuffed shirt on a personal level.
Himmler and Göbbels, half wits with a licesnse to ramble. Neither likely could hold my attention.
As for Hitler, I certainly would have listened to his goings on; particularly the small talk. The vegiteranism he was heavy on would be a problem, but I could work around that.
I would likely end up in a sidebar with Speer since he is the only one of the bunch with more than half a brain. Maybe we would discuss construction and architecural techniques. As for the rest I would follow my addage: Never teach a pig to sing. It wastes your time and annoys the pig!
But, a good single malt scotch with a wonderful cigar might salvage the day.....
