> They can't. Russia simply cannot control the tens of millions survivors of it's brutal invasion even if they manage to defeat the Ukrainian army in the field, which they can't. Well, there's no need for millions of survivors in wars. Right now, Russia is keeping it's line about "Ukraine is Russia" and with that, reasonable restraint towards civilians compared to Syria, but, if that is no longer "necessary" or "reasonable" in their point of view, using nukes and leaving no survivors is a cheap, cost-reducing strategy.
