Are you American? Because if you are from the country that dominated the world since WWII it feels different than being from the rest of the world.
Bretton Woods gave the Americans an "exorbitant privilege" that basically meant the US could live extracting wealth continuously from the rest of the world.
Then later the petrodollar system was established. People needed oil, the US would protect the Arabs with its immense army (financed with the dollar system) and in return the oil had to be sold in dollars, so all the world needed dollars if they wanted energy.
The US could just print dollars, and the rest of the world would suffer inflation.
That was great for the US for sure. Why not continue? Because the rest of the world do not want to continue supporting the US system.
The US was ok with Sadam using chemical weapons against Kurdish civilians until he decided to change the currency for paying the oil to euros.
The US does not want to de-escalate if that means the world stops buying US bonds and suddenly they are bankrupt and can not pay its debts exporting inflation to the rest of the world.
If Americans suddenly lose 50 to 70% of purchasing power then there will be war inside the US, not outside.
Except America went to war with Saddam Hussein a full decade before the move to the Euro and was largely a reaction to the invasion of Kuwait.
