Choosing Georgia or Russia is a false choice. The West has heard this kind of talk before - from Hitler, asking them to make a choice between Czechoslovakia or Germany; or Poland or Germany. The Russians are getting their tactics right from Hitler’s playbook: “German citizens are being attacked in the Sudetanland”; or “Germany is being attacked by Poland.”
Where does Russia go next? Ukraine? The Baltics? Poland?
And simultaneously building their case in Ukraine even now.
It's because Putin's a fascist. He probably goes to bed at night with "Mein Kampf" under his pillow.
The Ukraine seems to be next. There is a peninsula called the Crimean Peninsula where the Russian Black Sea fleet is based. The Russians lease the base from the Ukrainians (lease runs out, I think in 2012). Many of the people on the peninsula speak Russian, and I think Russia has given them Russian passports as well. Look to Russia “freeing” the Crimean Peninsula next.
The Ukraine most likely. It has a similar "Russian" sub population. It's not a member of NATO (yet!).
Poland, Estonia, Latvia and Lithuania are NATO members. An attack on them would bring automatic response by all the member nations, or kill the Alliance as some wimped out.
