Russia can't win a war against NATO, so they will not attack Poland or Germany. Maybe Moldova or something. This fear mongering is ridiciouslus. They can't even win against Ukraine, for crying out loud. Poland, France, UK, Germany(, Turkey?) would together crush them in a couple of months. Add Finland and Sweden and it gets reduced to weeks. Add the US and it'll take a couple of days. (Hyperbole, but still).

They are hopelessly outclassed in all categories but nukes. And UK/France has a couple of them, so Russia can't nuke willy nilly.
