It is my current view that this BBC article and the recent announcement by national security advisor Powell are conditioning the public mind not for an actual hot war, but for a "tough winter" of eye-watering price rises, possible shortages, and maybe even utility supply problems if we are particularly unlucky. While talk of war increases, a glance at the state of the military suggests to me this is unlikely. What we have is rather limited, and even that is only about 1% deployable within 6 months. Much of Europe the same (Poland being an exception).
That said, I also believe that there is fairly widespread, low intensity, grey-zone action across Europe at the moment. Not every random fire or infrastructure failure is "The Russians", but I'd be surprised if none of them were. Indeed some of them have already been formally attributed.
