Twitter is chock full of hyperbole, ignorance and deception. But one of its special qualities is that if you take some care and follow some basic rules you can find people who you can actually learn quite a lot from. They’re out there. And during chaotic and fast-moving news events you can learn a lot from them. One of those people is Michael Kofman, who is one of the people on my list of people to follow to keep track of developments in the Ukraine Crisis. Among other things he’s the Director of the Russia Studies program at the Center for Naval Analyses, the main Navy/Marines think tank in Washington, DC. His opinions may be right or wrong. But given the Navy’s/Marine Corps’ interest in keeping tabs on the Russian military we can be confident he’s highly knowledgable about that topic specifically. I’ve been following his commentary over the last week or so and yesterday he posted a lengthy Twitter thread about what we’ve seen over the last three days.
