I'm looking for specific and non obvious answers. Give me something visceral, rid the world of a figure or nation you hate. Preserve a culture you adore. It doesn't have to make sense either, you are basically god here.
What I mean is don't just say you'd get rid of imperialism or colonialism bc no shit
Personally I would make it so that the Americas are never discovered by the old world and every "would be" conquistador (especially cortez and pizarro) explodes.
Maybe have capitalism simultaneously start in India and China alongside Western Europe so we can see how much current timeline capitalism sucks because capitalism sucks in general and how much current timeline capitalism sucks because the Occidentals are an avaricious warlike tribal people with no regard for the sanctity of life.
