As someone not from the USA, I need to tell you, this is so much bigger than just the USA.
I seriously believe that a Biden presidency will allow the overtaking (or at least equalising) of China to the USA as the world's greatest power, ushering in a new world order where the world must bow down to China. It is a world where Iran flourishes and Israel suffers, where the EU leaders rubs its hands with glee and the rest of us suffer.
Trump staying in power is literally the difference between a good world and a miserable world.
Someone has been reading Peter Zeihan, I see :)
"The Shale Revolution" was a good book and makes some interesting predictions. I'm not sure that all of the wars he predicts would necessarily happen, but it's an eye-opening take on the geopolitics of today.
