If you mean nuclear war...it's over in about 40 minutes and all anyone cares about after that is survival. If you don't have some hunting/camping/farming experience, you probably won't last long.
I need more details here please.
What countries are involved?
Is the fighting near me? or can I go about my daily buisness on most days?
Is, Food, Water, Fuel in short supply? Is the extising infustructere in tact?
Can I buy supplies I need with current US currncy or will a barter system be in place?
Turn warlord and bide my time.The strong destroy the weak,the smart wait for the strong to slip up.
Go find that girl I text in Lincolnshire
I do not make silly plans for situations which are likely not within my lifetime, nor within my control.
Grab my towel and stick my thumb out.
i would relocate to Australia, the most peaceful country out there and not easy to get to.
I don't know personally
Probably die.
Detail your plan
