I think the navy officer you're talking about is william tompkins.
From what I userstand the nazis, a human looking ET race from orions and reptilians were in antarctica.
In operation high jump US went to wipe out nazis in antarctica around 1946.
The reptilians and Orions with their flying saucer crafts absolutely destroyed the 5000 manned US fleet in 30 minutes. All their latest aircraft carriers and planes destroyed.
The US thought it was the germans that wiped out their fleet.
Then the orions and reptilians went to USA and tricked them. They told USA that they will solve the nazi problem but the reptilians and orions wanted bases in the USA and wanted to be allowed to kidnap humans.
The nazis then went off into space and made bases on the moon, colonies ceres and beyond.
The nazis needed man power so made a treaty with the USA. Basically allowing nazis to kidnap people.
Nazis also infiltrated all major corporations and banks in the USA. The top leaders of these corporations were working for the nazis giving them money and all new technology discovered in the USA was given to the nazis.
Watch this video as it explains a lot.
