The world is thrust into a WW3 scare event with nuke sirens blaring(1), a water event(2), stock market crashes(3), and global martial law(4)
(1) It's Christmas at ground zero,
there's music in the air!
The sleigh bells are ringing and the carolers are singing,
while the air-raid sirens blare!
(2) A megatsunami? Floods or/and droughts? Someone inventing a synthetic version of water that is to real water what margarine is to butter?
(3) That is at least a familiar event, it has happened before.
(4) What would have to happen to make all the world’s countries agree to impose martial law at the same time?
