Hey Mark, have been watching you for a while, for years in fact, primarily in youtube videos by Garland, Nima etc. Since I have just missed the weekly Q&A, i would like to ask the question here, since it is directly related to video you have made with Garland: You have been mentioning this "mathematical box" that Russia is trying to stay in wrt to the conflict in Ukraine. But since the europeans have wasted vast amounts of its interceptor stocks to Ukraine and also transferred vast amounts of actual air defense systems, they should be very weakly defended. Why does Russia not decide to perform decisive strikes against key military transport hubs in europe, or drone factories to show the west: "You are not invincible, and your article 5. does not scare us". I personally, just like Karaganov do not think they will dare to invoke article 5. Would now, out of all the times, be the best time to scare them off ? Can Russia not take it?
