America may be plunged into an insular war with itself, Putin will see this as a green light to invade the rest of the Ukraine, after easily taking Crimea, thus declaring war with a weakened Europe, after the Brexit fiasco in the UK.
He will push the leaders in Germany and France to make a choice. He will destabilise Europe.
What is left of NATO, will rally their defences and plunge the cointinent into another pan European War. Gt Britain will remain idle because it will still be waiting on a trade deal with Trump, and Trump will never upset Putin. So the country with two poorly armed carrier groups and 124 Trident nuclear missiles, will sit idly by as Putin sets Europe ablaze.
Or maybe not. Let’s hope Biden wins, shall we.
