I thought price increases were being driven by fiat money printing, sending pallets of that money to Ukraine, and high energy prices due to that conflict.
Price increases were driven by supply issues resulting in price increases. Then companies realized that customers don't react to the amount of price increase, merely to a price increase.
Why bump up prices by 5% when you could bump them by 20%?
Fiat money printing didn't directly impact pricing unless you consider a lack of demand during a drop in supply but put another way "people didn't starve during the market problems" doesn't sound so bad...
Certainly a lot of money was given to investors which certainly made the housing crisis worse given it was considered a safe investment for the excess money.
Ukraine is mostly getting old equipment and listed at its purchase price...
High energy prices are due to increased demand due to global warming increasing climate control costs hugely.
The US economy is hardly as isolationist as you seem to think. Do you have any idea what the embargo on Russia did to the EU economy (hint: we didn't build those massive pipelines because we liked looking at them)? Let alone the massive loss of productivity in Ukraine, which had a relatively high level of education compared with other Eastern European countries while having very low wages? Not to mention the hit to world food supplies (which of course has less of a direct impact on the Global North as most of the food produced in Ukraine goes to the Global South).
And this is while we're still in a global pandemic that was still causing occasional lockdowns and shutdowns in China by the end of last year, causing ripples through global supply chains. Plus the short outage from the accidental blockade of the Suez Canal and the lasting effects from the 2020 disruptions of supply chains and mass death of small businesses. Not to forget the increase (and increase in severity) in droughts and floodings and wildfires and other natural disasters which have also been messing with production and supply (e.g. I know of several major insurance companies in Germany that are currently completely backlogged over claims relating to recent severe weather incidents).
There's a global ongoing financial crisis and it's neither concentrated in nor entirely caused by the United States. Yes, individual incidents (e.g. the SV Bank failure) have global knock-on effects but this cuts both ways.
EDIT: I don't fundamentally disagree with you. I just want to point out that energy prices aren't the entirety of what's fueling the ongoing situation and that it's a bit bigger than just the invasion of Ukraine, which is already disruptive enough (after all this is why we didn't have any major land wars in Europe since WW2 excluding the fallout from the fall of the Soviet Union).
