I was asked today what I was following on Ukraine as my links have been short of stuff related to how the conflict was going. Outside of the Institute for War stuff, the best stuff is found on YouTube and (shudder) Twitter. Below is the top pick of my current Ukraine sources if I could only pick one. You have to wait until about half way through his videos for them to get past the fluff and and into the good stuff. So far I have always found them to be educational once I got to that point (but I have not been watching them long). He has been pretty good about putting out one video a day.
