Oh I understand that. I was just being facetious; my point was more to do with the definition of a hole, and how it’s used here to describe something that definitely is not a hole.
If we’re pedantic, then the doughnut hole is the middle bit of the original doughnut, now that this part has been punched out.
I can’t speak for every country, but I know that the UK (where I’m based) is looking at a GDP shrink of around 1%; though given our ‘special relationship’ with the US, and our FAFO era with Brexit, we’re probably more dependant on American trade than your average long distance ally (or should I say former ally?), so I could definitely see other countries breaking even or even profiting from it.
