they have a history of putting down resistance to their empirial ambitions in sometimes brutal ways
Just like Germany, then.

I sometimes wonder how much Germans (and many other peoples) are actually aware of their own countries Imperial and Colonial activities. Germany had many colonial interests around the world (including African and the Pacific colonies, and the only reason they were not more extensive is that they had effectively been left behind in the race to plunder other countries natural resources. Something which Kaiser Wilhelm II himself actually lamented, stating that "Germany has begun her colonial enterprise very late, and was, therefore, at the disadvantage of finding all the desirable places already occupied." Hmmmm.
What is now modern day Namibia was a former German Colony (with a greater landmass than Germany itself), and also the setting for the first (German perpetrated) Genocide of the 20th Century. Rebellions by the Namaqua and Herero tribes were ruthlessly and violently quashed, resulting in some 120,000 deaths. There are also allegations that desert wells were systematically poisoned by the German colonial army.
So, the fact that Germany was a little 'late to the party' is the reason we are not now talking more about its colonialism, they 'missed the boat' as it were.
There are many shameful and abhorrent episodes of British colonialism, slavery in particular (and which I personally was educated about as a child at school) but the point being is that Britain was hardly 'alone' in this vile enterprise, they were just ahead of the game.
I do not blame modern day young Germans for perhaps feeling that they are being unfairly vilified ('the son cannot be held guilty for the sins of the father'), but this 'other countries did it too' moral relativism is a little off the mark.
The British Empire
never had a systematic, centralised, organised bureaucracy and infrastructure dedicated to and formed with the
sole and express purpose of murdering each and every race on Earth different to them, or all other groups who did not conform to some perverse 'ideal'. All of them. Each and every one. Man, woman and child.
That is the key difference.
More on 'concentration camps' later maybe, I'm off to the pub lol. Have fun peeps.
Err, maybe not. Was this thread ever on topic? LOL. Waaaaaay OT.
Cheers.
