Following an informal discussion with a student at work - were the WWII nuclear bombings of Hiroshima and Nagasaki war crimes?

Caveat 1: By your standards, not international law at any given time.

Caveat 2: No, not a poll, this is a highly nuanced argument which doesn't benefit from "click a button yes/no".

Me? I tend toward yes. I get the arguments against e.g. demonstrating the weapon in an unpopulated or military-only area, but not convinced.

@_thegeoff I also tend towards yes, but I also feel like the firebombing of Tokyo and Dresden was actually considerably worse.

War is hell ๐Ÿ˜Ÿ

@krans Yeah, none of it was fun. Carpet bombing cities had much the same effect, minus the fallout, which the military didn't even realise was an issue.
@_thegeoff
Yes! Innocent civilians slaughtered.
@brentk <devils adocate> Japan had sworn to fight until every person was dead. Minimise total casualties in the long run?
@_thegeoff
Hirohito was a tyrant. After the war USA allowed him to stay in power. USA loves its dictators.
@brentk Part of the problem is that Hirohito was a god. In some views at least. It's not a negotiation with a political power. War is bad enough without religion becoming involved.
@_thegeoff
Lets not forget the USA bombing of Dresden in Germany. Neutral city was almost wiped out.
@brentk UK also targetted dams which caused mass casualties, including slave labour. Then we agreed it was bad. And yet...
@_thegeoff
That's another strange thing. England would have enslaved Americans given the chance and then later it was comes USA happy to save it from Hitler.
@brentk @_thegeoff how exactly was Dresden a neutral city?!

What happened in Dresden in February 1945 was apocalyptic.

@brentk @_thegeoff even what you link says:

โ€œDespite postwar claims that Dresden had no military significance, it was in fact a rail center important to the Third Reichโ€™s faltering war effort in the East. There were also factories engaged in arms production there.โ€

@_thegeoff I wrote my master's thesis on Charge 2 of the Nuremberg Trial which was crimes against peace. I think an argument could be made that the dropping of the nukes and the firebombing of Tokyo could have been considered war crimes. While all 3 cities were legitimate military targets there was no attempt to hit purely military targets only. It was indiscriminate. You could not even argue mistakes hapoen and bombs don't always hit the ibtended target. Here the entire area was intended.
@legalquilts They were purposefully detonated well above the ground to cause damage on city scales. The argument being (I don"t need to explain) that the populous had to see the results in a way the Japanese government couldn't possibly dismiss.
@_thegeoff which meant civilians could not be protected to any extent.
@legalquilts There had been leaflet drop campaigns for other major bombings of Japan, there seems to be some argument over whether they were used before Hiroshima and Nagasaki?
@_thegeoff okay they warned them. But there was no effort to only hit military targets lije warehouses, factories and the like. Sure hones get hit by errant bombs but they aren't the target.
@legalquilts It wasn't for a moment an attack on a military installation, they just made sure to include one as part of target selection to tick an ethics box. And hey, bonus military target.
I'm not being controversial in saying it was purely a demonstration of a small city-killing weapon.
@legalquilts @_thegeoff I think some argued that the whole of Japanese society was militarised, so there were no civilians. Bit of a stretch.
@_thegeoff Problem with caveat one is that something being a crime is defined by law, not feels, vibes or gut. Doesn't stop the law being an ass though.
@DreadShips In this context, I'm more interested in real people's opinions than the courts of the 1950s.
@_thegeoff sure, but the war crime phrasing is a distraction from the actual question of whether it was right to do or not
@_thegeoff fwiw though, by the standards of the day it wasn't uniquely horrible in either intent or impact. At same time those standards were absolutely not those that (post-war Western) society would accept today.

@_thegeoff and to be honest I have more problems with the bombing campaign in Europe in 1944 and 45. Arthur Harris at that point had one of the most destructive forces in history under his command, but he regularly ignored intelligence reports and requests from other branches of the services in favour of simply flattening cities.

Every single one of those raids involved his men dying. He had a responsibility to sacrifice those lives wisely. I don't believe he did.

@DreadShips Barnes Wallace, Oppenheimer, "WTF have I done?" Seems to be a thread.

@_thegeoff Very much eyes wide open.

Going back to the original question, what would I want your student to learn from the conversation? That morality and legality are two separate things, and that the decision they'd make in 2023 is not necessarily the one they'd make in 1945. I doubt we're too far apart on that.

@DreadShips
Not really a history thing, more that students like the spectacular explosive stuff, so we're talking about nukes. And I wander into ethics in science a bit.
@DreadShips I see that as a different question that can't be answered without being able to see a multiverse.
Would killing Baby Hitler be illegal? Yes.
Would killing Baby Hitler make today better? Complex...
