Putin is not insane, I said a while ago, mind you that was in reference to China, there are many paths to achieve the same ends. You can go down the old fashioned dominate take what you want path. or you can do the hard yards and trade and sacrifice over a long period of time.
Whilst China has done very well out of the system at this point, it may well not in the future hence other means may be needed. Russia on the other hand appears to be stagnant, and the dominate take what it wants path seems easier.

Yes Putin knows what we will do, and that is nothing. Its not that we don't see that, we know that and are just going though the motions of reacting.
As for airspace incursions, some discrimination needs to be done to work out whats happening here instead of jumping the gun. There are particular statistical probabilities it could all be a coincidence.
