How can we get a Europe of the modern day that includes OTL Belgium and Netherlands, a confederation of the Rhine with Alasce-Lorraine, Prussia, Poland, Bavaria-Austria, and Hungarian Empire (including translyvania)? Other nations are as OTL in modern times. I would think that this means no world wars after Napoleon. Also though, I am not really sure how the russian empire would collapse like OTL.
I might do a TL to this effect if we can settle on a good POD.
