But man is not destined to vanish. He can be killed, but he cannot be destroyed, because his soul is deathless and his spirit is irrepressible. Therefore, though the situation seems dark in the context of the confrontation between the superpowers, the silver lining is provided by amazing phenomenon that the very nations which have spent incalculable resources and energy for the production of deadly weapons are desperately trying to find out how they might never be used. They threaten each other, intimidate each other and go to the brink, but before the total hour arrives they withdraw from the brink. The main point from the author's view is that

Man's soul and spirit can not be destroyed by superpowers.

Man's destiny is not fully clear or visible.

Man's soul and spirit are immortal.

Man's safety is assured by the delicate balance of power in terms of nuclear weapons.

Human society will survive despite the serious threat of total annihilation.
