I can’t be bothered justifying this too much. Canada and Australia elections completely flipped in huge swings. India, China and Russia are a lot more chummy than they have been. Whole trade routes have changed like Brasil sending soy beans to China now. US is trying to directly punish Brazil with tariffs for sentencing an (rightwing) ex-President for an attempted coup. The US is bailing out Argentina to help the rightwing Presidents economic plan succeed. NATO, and hence europe, has had effects with Trump flip flopping. It’s hard to imagine Trump’s flip flopping and chaos talking about things like turning Gaza into resorts didn’t contribute to Israel taking stronger militant action in the middle east. USAID was dropped with projected deaths around 14 million.

True, large corporations still have large effects on legislation in most countries, and your own personal groceries / interest repayments may not have changed that much but I think that’s a bit different than trying to say there was little difference globally between these two people being in power
