alt Hacker News> Prior to Bretton Woods countries were well aware that no single country could be entrusted with the power granted in being the global reserve currency.
That's a misleading statement. First of all at the beginning of the 20th century the British pound was clearly the global currency - where a lot of the international commerce happened. Then towards the 1930s and later on the Dollar took over that role. But that role carried much less weight back then - globalization was still in its infancy and a "global reserve currency" as we understand it today simply didn't exist back then. Right now some Dutch pensioners money is invested in American, Canadian, Australian, German, etc. companies. And the parts for most consumer goods are coming from all over the world. Pre Bretton Woods basically none of this existed. This global financial system we speak of today is unprecedented and only exists since the late 70s - where most countries abandoned their currency controls (apart from the US and CH which never really had them).

Britain’s downfall was World War I
I agree that speaking of a global reserve currency is putting the cart before the horse, but I think the meaning was also clear. It was obvious that the 'foundational' currency within Bretton Woods was going to give its creator something that could be easily weaponized against other countries. And so they sought to make it 'impossible' to do that, but ultimately did so in a naive way - 'Here's all this power - please honor these rules that will punish you if you abuse it.'
