The following sentence is the headline of the Washington Post.
The same nuclear fears Pelosi has about Trump cost an Air Force major his job in 1973
I know the usual meanings of cost as a noun and a verb and understand the article. But the headline is vague to me. I guess that she fears like the major did but when I think cost as the verb which means make feel bad or suffer it doesn't make sense because the story of the major was published 2017 and there isn't any mention about him now.
What do the cost and the headline mean?
