[Fallout] Could the world ever return to a pre-war war state?

I don't necessarily mean the culture or aesthetic so much as the global communications, infrastructure, and society thing.

Putting aside the obvious issues like radiation and deathclaws, which I would consider more tangible threats, I feel like there are much more intrinsic issues to be solved, if they can be solved at all.

You have things like a (presumed) lack of pollinators (it's nothing short of a miracle that enough survived the bombs to make crops viable), a reliance on pre war infrastructure and tech rather than attempting to redevelop it or manufacture new ones, and then of course the global resource shortage that kickstarted WW3 would likely still be present to some extent.

Yes, it could.  Arguably it already has in the heartland of the NCR.

One of the terrible ironies of the war is that the resource shortages that started it were solved a few years before the end.  Fusion power cells can take the place of fossil fuels and power an industrial society on a prewar scale.  Most American infrastructure had already been upgraded to take advantage of them, and the rest of the world could have been salvaged if it weren't for the nuclear exchange.  The war with China and resulting apocalypse was continuing largely out of *spite.*

The NCR, Brotherhood of Steel, and Enclave all have (well, had.  The NCR mostly poached what they have from the BoS and Enclave) the capability to produce new infrastructure and manufacture new power cells, rather than being forced to rely solely on existing prewar stocks.  Successfully building up to a prewar level of living is mostly a matter of maintaining a stable society, rather than any physical or technological barrier.
