And when ye shall hear of wars and rumurs of wars, be ye not troubled:
for such things must needs be;
but the end shall not be yet.
Mark 13:7
"Pope Francis warns that the escalation of the conflict in
Ukraine could lead to a “final catastrophe” that would “extinguish” the
human race. 
Speaking during his weekly address, the Pope said humanity would have
to “start from scratch” in the event of a thermonuclear war.
“Our imagination appears increasingly concentrated on the
representation of a final catastrophe that will extinguish us,” said
Pope Francis.
“What happens with an eventual nuclear war?” he asked.
“The ‘day after’ this – if there will still be days and human beings –
will have to start again from scratch. Destroying everything to start
again from scratch.”
The Pope highlighted how apocalyptic “flood imagery” is “gaining ground in our subconscious,” a reference to the Biblical flood narrative found in the Book of Genesis." IW
