| From my original post: "AND REFUSED TO PICK UP ANY SURVIVORS" In the absence of any threat (the ship was alone, and unarmed), then refusing to pick up survivors is ABSOLUTELY a TEXTBOOK war crime. Under the Geneva Convention, and under the US's own legal code. Thats not an opinion, thats a statement of fact. Exactly this was one of the charges against Admiral Doenitz at Nuremberg. |
Indeed, however despite being convicted of that and other charges, this particular charge was not factored into his sentence, precisely because British and U.S. submarines also engaged in the same practice during the conflict.
And that was with WW2-era submarines which were designed to operate mostly on the surface and could make provision for doing things like picking up downed aviators and engaging in "crash dives" to rapidly submerge.
Modern submarines are designed to operate mostly submerged and have very poor station-keeping while surfaced, and even lack the ability to crash dive (because you're supposed to be submerged long before you get into the danger zone and then stay submerged throughout).
It's not entirely uncommon for submariners on the submarine deck to die from fairly basic operations while on the surface (e.g. USS Minneapolis-St. Paul in 2006 lost 2 sailors this way: https://nationalinterest.org/blog/buzz/sir-men-went-overboar...)
