I don't agree. The Mongol Empire as an example is still remembered to this day. Nobody cares what exactly they did, but it's common sense that it was pretty bad. British colonial era? Same thing, but half the world still remembers what atrocities they have commited, and it was longer ago as WW I.
It's the bad things generations of people remember, the good things not so much. You know, hate sows war, war sows hate. The vicious circle as old as time.
> Besides, who remembers the British concentration camps?
Everyone, because it's the answer to the question "who invented the concentration camp".
Unfortunately it's the incorrect answer, because nobody remembers the American, Spanish, French and Paraguayan (the possibly correct answer) concentration camps that came earlier.
It's quite strange/interesting that atrocities in the "wars before WWI" got turned into atrocities in the "British colonial era" though; maybe people remember what they want to remember.
