But your original assertion is that American far-right movement is being exported to Europe. Now if you are going to stop precisely at the moment when European fascism (which has a big influence on American far right) died down, then obviously that's going to be tautological. So not sure that qualifies as American export to Europe.
You're making big semantic leaps here.You seem to be wanting to deny the claim that "the US are the origin of far-right ideology and pushing it to Europe", but that's not the point I'm making. My point is that, in recent times, the cultural flow goes this way. It's also one item in a list of other domains where the flow also goes this way.
