The answer I read from flamegrilled is, "not necessarily true". As in, could it be part of a larger loving plan?
If I could play "devil's advocate", and forgive me for using a human-led disaster Cofty, it could be argued that the deaths at Hiroshima and Nagasaki, the sheer horror of them, woke the world up to the deadliness of this new weapon, and national conflicts went underground (Cold War), peace talks got serious, and conflicts more local. Nobody wants to see the consequences of a THIRD world war. So some sense out of the senselessness. Like a teenager waking up to his own mortality, humanity as a whole decided, "Ain't gonna do THAT again."
But what sense could come out of a natural disaster? What could humanity possibly do to prevent a re-occurrence? Be more vigilant with our early-warning systems?
