You should realise this is quite the conflation. Might as well say we are going back to the age before penicillin because that was also "back then." I personally don't advocate for a return to the past for its own sake.
perhaps the US is doing that for other reasons (RFK Jr.) but the good news is that in the post US hegemonic order, that country can go ahead and collapse into flames and the rest of the world won't be taken down with it.
