As an old doll, born of parents born before the Second World War, living during the Viatmese , Korean,Cold, Falklands Yugoslavian, Iraq wars - and a lot of squabbles in-between - I personally feel these are scary times indeed , and I get where you are feared for your children
War is different to what we were (I ) was bought up with - pure cannon fodder - war now it techno based
We are never going into a war as depicted in the films that you have grown up with. , wars going forward are going to be technical
Tbh, and Im nor a doomsday sayer, , Id be more concerned about my own abilities to survive a complete shut down of tech - cos that's where the real threat is
