(excuse me if there's already a thread like this. Haven't been around in a while because I'm a bit busy and stuff. Besides, I think the other threads are a bit old anyway if they exist)
So this has got me interested for quite a while. I'm trying to wonder how exactly the Russian Empire could have joined the Central Powers instead. Perhaps Alexander II avoids assassination? Perhaps the Three Emperors' Alliance sticks? Maybe the Dogger Bank Incident is the cause of the war instead? Would the Nazis exist after the war? Would the US join the war?
The challenge here is to try to create a scenario where Russia joins the Central Powers in World War 1.
