One thing that might be worth addressing is the international condition post-war, beyond a few really weird-as-shit political shifts (Germany going back to an Empire) and territorial gains. Mostly dealing with the economic concerns of such a massive war going on for fifteen years.

To the major participants of the conflict, you have the obvious bit concerning a lot of young men and women being killed on the front-line, creating a significant artificial population dip in the national demographics. And for nations with a shrinking population like Russia this could catastrophic in the future as they get a ticking time-bomb that is a a massive aging population being supported by a smaller youth demographic. As a reference, here's the Russian population pyramid from 2010:

There's a bunch of Soviet-borns who'd be seniors by the time this RP picks up and just as many middle-aged Soviet-era citizens who would have children that would have died in the war. And already we see the patterns associated with a industrial or post-industrial society, which is a stabilized or even shrinking population brought from across the board economic potential that would distract from child bearing and family planning. There'd be a dip like what is seen in the 65-70 demographic who found WW2. So project that on the current 10-20 year old demographic(s) and you got another huge cut being made to the working-age youth.

And Russia already has issues with keeping its army full because there are so few service-age people.

And others:

So we got a future population crisis in many areas. And larger older populations make the issues of pensions a contentious issue as the state tries to keep money in the hand of their older generation and a smaller working youth population to keep the pension fund full.

On top of this we got the economic concerns in 3d printing to worry about and the changing face of manufacturing brought by it. Will everyone be the owners of the means of production to produce whatever they want or need? Or will the rites to produce be in the hands of those that already do, giving them more manufacturing power with less a need to employ? Either way there'll be an economic impact which'll only layer itself on the residual effects of war-time inflation (and someone somewhere has to pay for those bombs). Even if you weren't in the war you'll be feeling the pinch as interest rates adjust to inflation and the value of every other currency makes dramatic swings.

I have the feeling this isn't being considered when people continue to chant "reconstruction". Reconstruct with what exactly? Who benefits? How does it benefit? Who hurts? How does it hurt? What post-war political, philosophical, and economic questions remain post-war? What of the fate of armies? With so few service-age men and women in many top-powers there'll be that contentious matter of how to supplement the empty ranks, and how to effectively field a modern army at lower costs.
