As for Georgia, they are a sovereign state and can make their own decisions. If they want to join and meet the criteria then let them join. How is Georgia any different from Finland in that regard?
A policy of aggressive containment keeps us safer by wasting Russian resources. When we surround them with hostile powers they have to spend more on defending their homeland and have less for building nuclear weapons or launching invasions. Keep them poor.
And anyway you haven't even proposed a viable alternative. There's no point in negotiating with Putin: he doesn't negotiate in good faith. Even if we gave him huge concessions now he would just come back and demand more in a few years. Nor are we in a position to be able to offer the type of concessions that Russia seems to want. Ukrainian territory and Georgian sovereign freedom of action aren't ours to give away. The citizens of those countries will have to decide for themselves.
