As we all know, the War between Ukraine and Russia will be unfortunately a nuclear war, possibly turning into World War III, that entails a massive destruction of all life in this planet. Even thought someone could survive. The current civilization is going to regress and they’ll have to start again.
I don’t know how mankind will fight in the World War III. But I only know how they will fight in World War IV, with spears and stones.
This conflict will be horrible to all sides, since today we are used to live in peace, and we aren’t unable to hurt someone.
