He’s right. Military might will not do it, no matter how much. What will finally defeat Russia is Russian internal politics and economics, in which the “special military operation” is already a corrosive catalyst. What’s needed for Ukraine to win is enough basic military kit, timely provided, to keep the Russians on the back foot, while their economy deteriorates and the mothers and wives of the cannon fodder they so cavalierly mobilize get mad enough to speak out. That’s already happening.
The “military aid” that Brandon is providing does not include air power, just drones and missiles. The tanks provided were so loudly proclaimed months in advance, that the Russians had time to plant hectare after hectare of mines and fortifications. But that means that they are just defending grounds already taken, not significantly advancing.
Militarily, that’s totally half-a@@ed. But so long as Russia remains bogged down, and Crimea has become an arcade shooting gallery, the politics and economics have a chance to undo Putin, making further military adventures by the big bear more unlikely.
