This is part 5 in a 6-part exchange between Konstantin Kisin and myself. I will be writing parts 1, 3 and 5; Konstantin will be writing parts 2, 4 and 6. The subject of our exchange is whether the West is following the right strategy in Ukraine. Konstantin and I have previously discussed the issue on my podcast, as well as on Twitter. We are now doing so via this Substack exchange.
