In what ways are you saying "Europe is absolutely obsessed with the US": politics, tech, capital markets, defense, economics, culture, cultural trends, unpredictability, something else? And how is that "obsessed" rather than "paying attention to"? Without you giving any specifics, can't tell if that is good-faith comment or trolling. For example US audiences are obsessed with Downton Abbey, or the Titanic, or the 15-minute city proposal, and Tarantino was obsessed with French names of McDonald's hamburgers, but noone built a broader claim on top of those.

What specific event and year were IYO the onset of what you're claiming?
