As evidence that the US Dollar plays a large enough role for this to be the case, half of the banks bailed out in the TARP program were foreign to the US (https://www.europeaninstitute.org/index.php/ei-blog/106-augu...) and trading is US Dollars.
Yes.
The BRICs economic group has been trying to launch their own currency for a while now. This is one of the reasons for it. Trump has threatened to impose 100% tax on them and on anyone else who ever tries.

It's only been Russia (and to a certain extent China).
India and Brazil have both vetoed any attempt at a "BRICS Currency".
I'm ambivalent about it. Having our own currency is good, even better if it's not backed by USD, best of all if it's backed by precious metals like gold. On the other hand, I hate Lula and everything he represents so much I actually want him to piss Trump off to the point he sanctions the entire Latin American continent until Lula and his fellow communist dictator friends drop to their knees and beg for mercy.
When the economy is backed by something real, credit generally keeps up with the broader economy. It can't expand beyond reserves of real resources. Now that the money is not backed by anything, credit can expand infinitely. Credit generates most of the inflation which is a direct and ever increasing tax on the poor. It has been going on for half a century and shows no sign of stopping. The best part is even the mere attempt to stop it will cause a meltdown since the economy is addicted to credit.
So, leaving the international system helped the European economies greatly then. It makes sense some other countries are having the same idea now.
Correlation =/= Causation.
The Great Depression was caused by American overproduction and a lack of domestic buyers who could afford to purchase American goods (sound familiar?). This was back when America was still functionally a developing country.
Brazil has gone through numerous currencies. They have all gone to zero due to hyperinflation. One of the top Brazil stories on HN is about the way the government conned the population into believing that this time it was going to be different. We are also about to launch our very own central bank digital currency.
Foreign entites tend to earn in foreign currency, although not always and which is why China for example recyles a lot of the US dollars they recieve back into US government bonds. However the whole thing opens foreign governments and entities up to the risk that the relative inflation rates will affect the currencies (which it does).
I also think that the USD is currently under attack as the reserve currency and running these deficits is a way to protect its position.
We will see in a couple of years how things play out.
