Let me be clear: If it weren’t for the English Channel, Hitler’s panzers would have overrun Britain as effortlessly as they did the rest of Western Europe.
GB suffered tremendously during during WWI (as did France). It’s losses were incomprehensible to most Americans who probably still don’t grasp it to this day. I’ve seen the figures. Between the wars, a huge pacifist movement took place, the economy was horrible, taxes were high and unemployment rampant.
True, you still had your empire, but mostly in primitive areas in Africa and the Middle East which were at the time easy to exploit and subjugate.
Let me be clear, you are talking nonsense. Both about an invasion of the UK and the power of Britain and the British empire.
