I was curious, so I looked. He's out there boosting Timothy Snyder. Oof. I'll pass.
"Since Russia's 2022 invasion of Ukraine, and the bombing of its energy infrastructure, Snyder has spoken and written widely on the history of Ukraine and its worldwide importance for democracy, on the disastrous geopolitical effects of the invasion, and on the need for other nations and individuals to stand for the protection of territory belonging to that state."
which seems reasonable to me.
It's far too much "trust me I'm an established intellectual" and far too little evidence-based reasoning for me. To each their own.
