It seems like the danger even bigger than Russia is government incompetence and the system of broken incentives where everyone does everything to appear busy but actually solving the problem.
If there's a drone there, and you don't want it there, the solution is obvious. It's obvious enough to any nutcase in the US with access to a shotgun (with various degrees of success, but at least they're got the right spirit). If nobody's taking out the proverbial shotgun then I have to assume the drones are not an actual problem and merely yet another excuse for busywork.
Edit: I am not saying to literally use a shotgun against them. But offensive solutions need to be developed and put to use; otherwise if we sit helpless now, what will we do when those drones evolve and start carrying offensive payloads? Fear-mongering and finding endless excuses about not doing anything is not going to help.
