The United States vs The World
Everyone else is doing is, my turn for an off color topic.
What if the US elected a leader so deranged (Nor saying Trump is such a leader 😈), that he wakes up one day and thinks, "The world would be a lot safer, if there was less of them then us. Preferably, none of them."
And then he tries to alpha strike the entire world into extinction.
How much of anything would he left? Just an all out, genocidal attack from all sides. No taking territory, no surrenders, no quarter asked or given. Fight to the last man.
Just the US against everyone else.
