Shek: "Given that, however, it is still not a big fundamental issue."

It's a subject on which I'm not competent to have an opinion, but "a potential regime changing event" is in my opinion the current expert consensus.

Whether it will actually be regime changing is something the big guns in economics and global finance have debated over the last decade, with strong opinions on both sides. Since the result will determined as much by political as economic factors, it is imho unknowable in advance.

As for the post-WWII order, I suspect that few non-experts can explain how the system changed functionally (not conceptually) after the end of BWI. To future generations the shift will be considered trivial imho, perhaps like the differences between the component wars of the Hundred Years War, between Marlborough's various wars, or between WWI and WWII.

On the other hand, I'll bet the end of the US dollar based order (1945 - ????) will be in the history books.
