Bunch of nonsense. None of the examples you cited from other times had any remote comparison to the literal collapse of the global ecosystem. What do you get out of arguing that the level if crisis we're in is not so severe that humans civilization is going to collapse and that there's nothing we can do about it? At least with MAD, the most severe of your comparisons, there's an implicit reason why no one fired nuclear weapons. There is no recourse for what is happening on Earth right now. I'm actually kind of disgusted by your comment.
