Russian troops have invaded Ukraine, this is not in question. Whether or not they have the official sanction of Russia itself or are merely “on vacation” fighting for a good cause is up to the reader to decide. The main contention so far is what exactly Putin is doing by playing a very silly game by trying to invade without invading, telling the world a fairly transparent fairy tale that no one believes
I think that the key question has to lie in Putin’s head, which is to say how he is responding to the forces on him. That requires a lot of speculation in the absence of any good information. Good reporters (and bloggers) don’t go deep into speculation, so if you don’t want to read this I’ll understand. But it seems that Putin is eyeballs deep into a war he can’t lose but also can’t fight.
