Also, does anyone else pay attention to the enforcer channel?Some, but not all that much.
Here are a few of the channels I watch on the Ukraine war (and war and international politics in general):
Reporting from Ukraine: Daily updates from the front. A bit gung-ho, putting a positive-for-the-Ukrainians spin on most everything... But can you really blame him? (And not all that hard to discount for.) Interesting look into the detail level anyway.
Anders Puck Nielsen: Warfare analyst / lecturer at the Danish Military academy. Very thoughtful and insightful perspectives IMO, not just on actual warfare / strategy, but the wider political side too.
Österreichs Bundesheer: General Austrian military stuff, but with occasional (couple months in between?) analysis of the Ukraine war by a colonel at the Theresianische Militärakademie. (Dunno if these videos are also available there.) In both English and German, should be next to each other on the Bundesheer channel. Thorough, but a bit wooden; I prefer the Dane.
Militär & Geschichte mit Torsten Heinrich: Haven't watched him all that much recently; I have a feeling he used to be better. Mostly in German, but occasionally in English (although that seems to be rarer nowadays, as I just looked through his channel).
Perun: By an Aussie, apparently originally a gaming channel, but great (hour-long-plus!) weekly deep-dives into some aspect of the Ukraine war, war and strategy in general, international politics, arms technology, and the intersections thereof.
Zeihan on Geopolitics: Kind of the opposite of the preceding -- American, short videos, but many more of them. Feels a bit pompous much of the time, and does tend to harp on about demographics, but... Can't say he's wrong about much of it.
William Spaniel: The "Lines on Maps!" guy. (Scroll down a bit and you'll come to a video were he explains the concept. In my economist interpretation, his lines are kind of supply-and-demand curves but with a geographical twist.) Maybe a bit sensationalist occasionally, but quite OK. And his ongoing series of "Peekaboo!" hallenges were fun. ("Where's Putin? In my last video, he had snuck [=Spaniel had pasted him] into the crowd at an American mall at 12:34. So where is he now...?" Dunno if he does those any more, haven't seen it in a while.)
Oh, and for the historical background: Timothy Snyder: The Making of Modern Ukraine. Hey, it's only twenty-three videos, and they're under an hour each!
