> Yes, and we have plenty of infrastructure to destroy. It's a target rich environment.
Yes, but how is that relevant? Everything is always open for terror. Russia itself is not safe either. Or are you assuming Russia is out for pure blind destruction? Degrading themselves to become lousy terrorists? Just spreading destruction for no reason?
I would assume they at least will have some aim and reasoning behind their targets, which would mean they will come with soldiers and tanks, and conquer land, or destroy the highest profile-targets. In the first case, they will have very limited resources to spare for attacks on middle European targets. For the second case, you only need to focus your defence on those targets.
> I've seen zero indication that this is true.
May you are following the wrong sources? Building up drones-defence is in progress for a while now. Whether it's going well is a different story, but I would assume that they will not talk very openly about those things for obvious reasons.
