Second theory I saw argued for with some rather small degree of plausibility in Reich of the Black Sun, which covered everything from German bombs (redubbed Little Boy & Fat Man) that when captured ended up breathing life into a mismanaged, Thin Man-cursed Manhattan Project- the fissile material for which were produced/derived from a chemical liquefaction process, this extensive project insulated from the more well-known and botched 'hobbyist' programs and further obscured in the concealment of production within a false buta synthetic rubber plant, for which at Nuremberg the managers are alleged to have defended themselves against their alleged slave labor use by oddly proclaiming 'not one ounce of buta rubber had been produced here' for the duration of the war- as well as foo fighters powered by electric universe gravitic drives, a German-buoyed Japanese bomb project finishing a day late & a dollar short with testing being done in the Korean peninsula (acting as a prime under-the-hood reasoning for the conflict between the dialectic Capitalist-Communist blocs there) and other bits & bobs like DEW weapons. This bomb project and its children were situated in remote facilities north of the Alps and west of Prague, and were a contributing reason for the rush north on the Italian front.
And, as usual in this sort of literature, the usual 'ebil Nazis infiltrated and control our government! (((Eisenhower))) warned us about the goyish military-industrial complex!' spiel. One Hans Kammler, an overseer for SS construction and secret weapons, is the peculiar missing link for a number of these projects and for the bad goy secret puppeteers, with his living after the war posited by escaping with a multi-engine heavy bomber/freight craft capable of crossing the Atlantic. Might've been the Me-264 prototype with some modifications, fuel in place of bombs, it's been a long while. Considering Kammler's living or dying in '45, to '47, or not at all are very muddy, it's as plausible as anything else that he escaped to South America (or some Antarctic bolthole, hollow or otherwise) using a long-range and effectively uninterceptible aircraft.
Overall, the emphasis should perhaps be on the 'small' part of 'small degree of plausibility.' But it was a rather interesting read at the time. Complete dead-end Thin Man did only get thrown out in July of '44, and Little Boy & Fat Man's readiness was only achieved post-May, plenty likely to be coincidence, but lining up with the looted bomb narrative. Personally, I'm going to be really, really radical here for the fun of it and propose a frame-world where all four theories are correct simultaneously; by completely throwing out conventional physics and starting from the ground up, this small number of ill-funded Germans, the Vril group, et al, keyed into some long abandoned electric/gravitic universe concepts of previous high civilizations that contemporary physics could not and cannot wrap around properly, after which world Jewry dispensed the semi-complete physical proceeds they had captured along with their manufacturers and used & duplicated what they could, then slowly running out of paperclip'd personnel & those tutored by them that can fully grasp & use the scraps of information remaining until the Bomb becomes a paper tiger, a limited stock of archeotech held in reserve and used as a terror tool over the populace at large. Silly, maybe, but an interesting line of thought.
