Is It a Real Challenge for Ukraine to Advance Base Air Defense?

This is not an optimistic episode. Michael Kofman speculates that the war might be in its most dangerous phase. Why is that? Ukraine's casualties and shortages in munitions are beginning to show as Russia is gaining some operational advantages in the Donbass. Further, Russia's efforts to fill its manpower gaps have been partially successful without relying primarily on conscripts and conducting a large mobilization. Ryan and Mike speculate that, in the end, this war will be decided by the country that can endure the longest, in terms of their economies, logistics, materiel, and political will. And Ukraine's endurance is tied up closely with the will of the West to continue backing Ukraine with arms and other supplies in a war that could continue to drag on for months, if not years.
