I think that’s a bit random in this case, but I did my best…
The main message is AfD is winning, which has been at least all over the news in Germany and I guess also in international media. And then comparing two dates, and the date of the invasion of Poland (and the start of WWII) should be well known in Europe?
But I did my best to fulfill your request.
There wasn’t a link to a source either. And I doesn’t like to link to a META platform.
I think it is okay the way it is.
