Here's what I don't understand:
In terms of their stated objectives, clearly Russia has the resources to take out the government in Kyiv and install a puppet. But we're talking about a country of 43 million and, while early, there is little to no indication of Ukraine soldiers laying down arms.
How does this work without a long counterinsurgency that will result in a lot of loss of life for the Russians? And does that counterinsurgency, seeing the tepid response by the oligarchs and the much larger-than-expected protests, cause additional domestic problems?
The whole thing kinda looks like an overreach, but he may not care.
