 :*Reply - Thanks for the comment. Look at Evans pg. 2 for an example of the two being connected under the banner of optimism. Also, I am not sure I understand your argument. Doesn't suggesting that the specific words ""nuclear optimism"" must appear in every reference would violate WP:NAD? Isn't that like saying that if a book only talks about cars then it is inappropriate to use as a reference for automobile? And regardless, why would this imply deletion rather than one of the other options.
