I think the whole “empire collapsing” is a bit of a dramatized phrasing, though historians can correct me. I think it’s much more death by a thousand cuts, and the UK is a great analogue in that regard. Look at Brexit, for example. Or Black Wednesday, from which the US’s esteemed Treasury Secretary profited handsomely.

The UK’s decline has taken centuries, though, and there are many events that one can point to. I think I agree with the grandparent’s comment about grandparents, about the arrogance of how things will continue to be a certain way.
