Allied bombing is a thing that happened, but sometimes it seems like people really strain to relate anything to something shameful associated with Americans.
Parent just listed two of the most brutal single attack conventional bombings of a city in history.
This could be due to some agenda to shame the Allies for their involvement in WW2, or it could just be because WW2 is really the only time in history it was done on that scale and the Allies happened to win the conflict.
I'm going to go with principle of charity and assume the latter...
It would be absurd to attribute every mention of Dresden or Hiroshima or whatever to an anti-American agenda. People simply inhabit an environment where that is what comes to mind. Maybe people don't see the similarity I do, or maybe the thing that I think relevant is obscure. But I'm noting that it sometimes seems strained and odd, from my personal perspective. Blaming an individual here and now was not my intent. I'm more saying, look at the bubble english speakers inhabit, I wonder how we got here, since most people doubtlessly aren't acting out of a conscious or malicious agenda.
In this particular context, if you're thinking of WWII, it's kind of odd for a person not to think of and compare the concept to https://en.wikipedia.org/wiki/Fu-Go_balloon_bomb
