What do you mean by “The British should be held accountable”?
Who, exactly? And how, exactly?
The monarch, the government, the entire population?
Reparations? If you sell everything - crown estates, crown jewels, all the art, everything - are you going to deliver $7.28 to every single person in a former colony?
How about we look forwards, instead? There’s little to be gained in trying to make current-day nations pay reparations for things that their ancestors did.
Not really - the current British royal house is german-descended. There are noble families in the UK with longer english/british pedigrees than the ~~Saxe-Coburg Gotha ~~ Windsor/Mountbatten family. But the current situation suits them better than rocking the boat.
