African slave trade. Look it up. I never said that Britain was a paragon of virtue in all things. I could list the White Paper and the sinking of the Struma just for starters, before going on to the concentration camps in South Africa and the massacre at Amritsar.
But is it your contention that the many past faults of the British empire makes them unfit to offer any help against newly revived Russian imperial aspirations to its present-day victims? Nonsense. If you want to play comparative empires, the Czars and the Soviets can’t shake a stick at Britain vis a vis morality, least of all Vladimir Putin’s kleptocratic dictatorship.
Any nation that embraces a eugenicist like Churchill, is racist to the core.
