IF we have to bring back the NJ we’re in a bad spot war wise and nukes probably have been used.
If nukes have been used, then nothing is going to be refurbished in the 25 minutes to an hour before the world is engulfed.
Its interesting to watch nuclear war films such as the Day After and Threads, and the animated films When the Wind Blows and Grave of the Fireflies. The books Alas Babylon, Panic in Year Zero, and On the Beach too. The human condition is both fragile and resilient; a paradox.
