why did anyone ever care about Queen Elizabeth?
She was like a God(dess) – not in terms of looks or personality, but
stature. Only comparable to the Pope in the Catholic church.
In an unstable world, if there was one thing you could rely on, it was that there was this queen. For over 70 years straight. She wouldn't let anyone mess with fundamental British values and traditions.
I think we can see that both the US and Russia are easily susceptible to fascism. Either or both of these countries might easily turn into another version of Hitler's Germany. (If it has not, in fact, already happened in one of them, and the other was a very close call last January.)
There is no one to watch over these two mamooth countries, which means they can descend into murderous chaos at any time.
The queen would never permit that to happen to Great Britain under her rule. In this sense, her role was anything
but ceremonial.
