I have proven that I have no understanding of the human element behind the Ukraine war. In fact, my understanding is so poor it has been almost a good guide in reverse as to what was going to happen. In other words, based on my past performance you would do well to think that the people involved will act in a way that is the exact opposite of what I think they will do. So why have I been so wrong?
It is tempting to throw up my hands and say that the Russians (or at least Putin) are irrational and that is why their behavior does not conform to my expectations. But even irrational people are predictable once you get to know them. Putin has been around long enough and lead Russia in enough conflicts that I thought I knew what the pattern of his behavior looked like. If you look at the conflicts in Chechnya, Georgia, Syria, and the earlier Ukraine conflicts it seems like a clear pattern becomes apparent.
The pattern seems pretty simple. First you prepare the justification for what you are going to do all the while denying that you are going to do it. Then you use overwhelming force carefully calibrated to be as risk free as possible to accomplish limited objectives. Last, you seek to reach some kind of accommodation that will end the conflict on sustainable terms. Russianphiles would probably argue with first part of this pattern and Russianphobes would object to the last part of this pattern, but to my eyes it still does a pretty good job of describing all of the recent conflicts that Russia has had save the most recent one.
