I remember having once read the claim that after VJ-day
(surrender of Japan in 1945), the entire world was at peace for 16 days.
16 days of world peace.
"World peace" is nowadays a distant, seemingly unrealistic ideal.
It's not something people would usually consider feasible any time soon.
Yet maybe we already had it, once, for a few days.
Maybe it's not that unrealistic after all.
