Air defense saturation would really limit the attacks from Russia without requiring hitting inside Russia. They’ve done great lately and that keeps increasing. But Ukraine hitting Russia’s launch sites that are responsible for their strikes (more?) would be great. When I envision how this could look if (when) Ukraine pushes them fully out, I expect Russia to keep shooting like this unless there is a drastic change… until they realize it is futile due to Ukraine’s defenses. That’s a hope anyway.
