Yes, that is true. What does it mean? Does it mean Germans were not ruthless enough? Does it mean the British were more humane and efficient?
Does it mean that the expansion of western civilization was a bad idea?
Figuring out what lesson should be learned is the hard part.
The Dutch colonializations didn’t earn any prizes.
The British, Spanish and Portuguese were less cruel than the German, French, Dutch and Belgian. Which is why the former have had a lasting impact
Also this and what he Belgians did in the Congo or the Feench in Indo china was not expansion of western civilisation. The Belgians and Germans were cruel, kill em all, the French were cruel. The Dutch were only in it for creating captive markets and suppliers.
