That didn't happen, though. We were "on the brink on WW3" right through the 80s, particularly when the Soviets shot down a Korean passenger jet. Apparently it was even worse in 1962, with Russian missiles being based in Cuba. Didn't happen then, either.
The fires, floods and now this virus causing Australians to go stark staring mad, strip supermarket shelves and stockpile items they don't need and can't use definitely have happened.
