I am not disputing the closure of my question on end-of-humanity SF and politics, but how could I edit it so that it falls within the rules of this Exchange? Seems I'm not the only one interested, it has four upvotes and one person favorited it.
I believe you can just go to the question and edit it, like you would a question that was open. If I'm not mistaken, this would automatically queue it for review by a moderator to see if the edit made it pass muster.
On a personal note, I think your last paragraph, "are there any scholarly works..." is what prompted people to vote to close, since it made it seem like an open ended list question. However, if you reworded it to focus on the penultimate paragraph, it can be a very interesting question - "What effect did nuclear fears have on the science fiction of the early cold war?" is a great question. Might still be a bit too broad, but interesting.
