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.
The EU leadership is currently so weak that I'm sure they are all compromised. The EU would be lost forever if Biden and the Chinese take over, but it doesn't have to end that way. We just need a few honest leaders with courage to do the right things, including death penalties for traitors.
