On a quick overview, I notice a few glaring errors right away. For example on image 13, the 'article' says that: "It is said that the first successful implications of this knowledge was seen as a result in the face of pulse-jet engines, which were designed for their V-8 rocket called as the “Buzz Bombs.”"

There are several things wrong there. The 'pulse jet engine' powered the V-1, which was called the buzz bomb by the British. There is--as far as I know--no German rocket called the V-8 which used a pulse jet engine. The article also uses images of V-2 ballistic missiles, which were powered by a liquid fuel engine. For that matter, the article states "It is said that..." but then makes no attribution of the claim. This is a classic use of weasel words, attempting to give a claim to more credibility.

The article also seems to be drawing upon long claimed conspiracy theories about "Ancient Indian nuclear weapons".

I will not comment on the alleged connections between Hitler and the occult, of any form, and leave that to someone who is more qualified.

However, given the use of weasel words, and the clear factual mistakes on something that is easily researchable, I'd be inclined to not trust the claims of this article. Furthermore, remember that extraordinary claims require extraordinary evidence. If the person asserting the claim is not presenting that evidence, or is presenting false or misleading evidence, then that should be a massive red flag.
