Yeah, thanks for the boilerplate. Exactly what mutual defense of the United States or Western Europe is Ukraine or Georgia going to provide? Western Europe and the United States is not under any outside threat, let alone one that these countries could meaningfully assist with. This is nothing more than "containment" policy, an attempt to restrict another power's freedom of action, which only works as long as they're weak enough to be imposed on. When they're strong enough to contest it, you're going to be over there fighting for Ukranian soil, and if you care that much, you should just volunteer and leave the rest of us out of it.
