I would get so annoyed by that, that I might not buy either.
I’d call up a good book store or research librarian, and ask them che cosa schifosa succedde with having two similar book titles by the same author and slightly different publication dates.
I imagine that they published the same book with different subtitles in different markets (different nations?), and that there might be some annoying editorial differences between the two. Maybe one’s for Germany and avoids mentioning Nazis? Or one’s for USA (probably the one which mentions the US: ”...Why the US Overlooked Putin” LOL) and/or is more stupid, or something?
I guess I’d try the one that doesn’t mention the US, because that’s probably the US market one. But it could be something else.
