It's been clear for a while global power is shifting to another region. I've always said when a currency fails, it fails hard and fast. Almost seemingly overnight if you aren't paying attention. USD is losing its world dominance as a reserve and petro currency. It's being done on purpose. (Hint: A new global currency is a lot easier to form threw fledgling trade deals and new economic partnerships than it is in an established economy). You also need a catastrophic economic collapse to usher in a new currency like that.
So you can protect yourself; You could move to that other region's friendly territories, and you might be able to shield yourself a little bit. As people said, you could invest in metals and properties to try and maintain some of your wealth during this transition, Or you could revolt against it (to your own demise no doubt)
I also want to add that it won't just be USD that suffers. Any currency that is tightly woven around USD (EURO, CAD, etc) will be affected as well.
I'm just trying to be realistic about what I see.
(Also i tried to avoid as much politics as i could!)
