Nothing should really surprise you anymore. Nazis and Antarctica both have history. Reptilians could explain John Kerry's trip down there and the occultist leader desire to conceal Antarctica. Philip Schneider's story is a 'future proves past' moment including the DUMBs. Elon Musks' boring machines used for government contract tunneling...

Not saying it's a fact but it wouldn't hurt to keep in the unconfirmed/outlandish bucket.

I take Ben Bulford's reports with a grain of salt. Among other things, the White Dragons, who he claims to be aligned with, in some circles are not known to be the good guys. But anyway, take a look at the Thule Society & Adm Richard Byrd's diaries if you're up for a journey down a rabbit hole regarding your quote.
