Maybe we Dutch ought to resurrect two similar panels just outside the cemetary boundary.
Two panels commemorating the contribution of Black American soldiers towards the liberation of the Netherlands in World War Two have been quietly removed from a cemetery in Limburg. It follows a complaint by right-wing think tank The Heritage Foundation to the American Battle Monuments Commission.

Op de Amerikaanse begraafplaats in Margraten is het opeens stil geworden rond de zwarte Amerikanen die hielpen Nederland bevrijden. Twee panelen die hun bijdrage herdachten – én wezen op hun strijd tegen racisme binnen het leger – werden zonder toelichting verwijderd.

China's human spaceflight agency stated today that the Shenzhou-20 crew spacecraft may have been struck by a small piece of debris. Impact analysis and risk assessment are underway, delaying the crew's return to Earth, originally scheduled for Nov. 5.

Once again urging archaeologists to critically assess the AI push into archaeology. There is a huge swath of problematic ethical issues that come with the AI tech & tech lords & we don't have to make it easier for them to insert themselves in archaeology by welcoming them in. Don't be complicit.

imo this is *not* space debris. It appears too fast for that. Rather, it looks like a slow fragmenting meteoric fireball of asteroidal origin, likely dropping meteorites. #Moscow #fireball
#BREAKING | A bright green fireball was observed streaking across the sky of the Russian capital Moscow at approximately 6:30 a.m. local time. Experts attribute it to space debris re-entry.
