Eh, not sure any more than most other mostly white nations. England is responsible for spreading like a fungus around the globe, and brought her own brand of white supremacy with it (which the US was an offspring of).
But I do believe overall the US and the world overall has progressed. Certainly we have a long way to go, and certainly we can point to backsliding in some cases. But the difference too is the large, vocal mass of voices around the world saying “this isn’t ok”. And while in the US and other countries one can point out specific issues, overall I don’t think it’s a fair caricature of what they area about.
