Who are they? The new generations that need to fight don't have these memories no they have any desire to die for anything. Many older East Germans are in fact nostalgic of the communist time and the younger generations are brought up with pacifist ideas and despise military. The German and French right are also pro-Russian. Russians will do what they always did. They will install pro-Russian local dictatorships that will rule the local populi.Na I doubt Europe would allow that. They remember all too well what Russian rule is like especially the iron curtain countries.
East Germany ( now combined Germany) would never stand for that again.
Russia is no match for a combined Europe, look how long Ukraine has been holding them at bay, a combined Europe easily outguns Russia in every way.
