Well, I did a search on "Ukraine war" on US Amazon and in the first page there wasn't a single notebook. All results were either for books or movies related to the subject.

I assumed Amazon US search would be similar, but that does not appear to be the case. I apologise for writing: "Try an Amazon book search for “Ukraine war” on Amazon UK and US and already the search results are populated with “Ukraine war” blank notebooks. This is only true of Amazon UK (see screenshot above). Thank you for posting your results and I apologise for making a wrong assumption, (I still hate Amazon search though!)
