I watched this highly informative video on Gaia and was impressed to understand some of the intrigue surrounding JFK's visit to Germany immediately after the second world war. Evidently, he was invited along by James Forestall, as they were personally close.
I suspect what they viewed and inspected there may have shocked them all to the core.
I've recorded about 6 minutes and recommended the watch if you have a subscription. The link is below the image.
