Is humankind regressing to another medieval dark age?

Is trust so damaged by toxic politics, deceitful diplomacy and preemptive wars that distrust is now the byword of today's world?

Is active preparation for war now the standard operating procedure in every nation?

With the ever-increasing ferocity and destructiveness of modern wars, cities will now have to build downward rather than upward.

Humankind will have to learn to live like the moles, digging underground and even undersea to build its living quarters and facilities.
