I predict that at some point in our lifetimes, and probably well before the present decade is out, we'll get to a cuban missile crisis like moment. I fear that the coved 19 pandemic will be remembered as the easy part of the 20 twenties, before things got really bad. An oil price crash down to forty dollars is entirely possible in the face of an oncoming global recession. A natural resource centric world war, where nations hoard rather than trade, natural resources, is entirely possible. And i don't see any way out of it long term.
