I've attempted to do a deep dive on this claim. The only source for this story is Soros himself. Nowhere else is there any suggestion whatsoever that Germany used Jewish children in the manner he claims.

Now, look at it this way. If Soros is part of the cabal, what better way to kill two birds with one stone: "I served evil Germany" (therefore supporting all the other lies about Germany), and also hiding the TRUE source of his seed capital which he used around the world to attempt to topple governments and financial institutions.

I find it interesting that everyone seems so willing to accept this evil worm's twisted lies so easily.
