As someone from a country with a long history with Britain and it's dark side. I have to say that if you had to choose a country to conquer you, it would have to be Britain or England more specifically as in fact it was the English who conquered the rest of us. They were ruthless in their conquests but in comparsion to the likes of the Nazis and Communists, mere puddytats. In the context of WW2, they were one of the good guys. In their overall history they were like all the others, sometimes good, sometimes bad.
It is the fate of the invader to be puzzled by the ingratitude of the invaded. After all, we came to your country defeated you, proving our superiority. We gave you our culture, our language. We included you in our empire and made you one of us. Why on earth would you want to be free of us? The English always suffered from that syndrome. Still do, to some extent. Almost as if they were doing us a favour by conquering us. The Romans were like that too, as were the Russians, the French and frankly Americans.
I say that as someone who has traceable English ancestors, though I be 100% Irish

So my own ancestors were part of the problem. That makes me one of the bad guys!

But the Brits are far from being the worst even though sometimes they were on the wrong side. But as often as not the greatest critics of the British were the British themselves. Which is a healthy thing for any nation.
