I think the big problem is that Putin is old school Soviet, with a little Napoleon ambition thrown in to the mix. He's trying to rebuild the USSR by the death of a thousand cuts. It's not up to us as Americans to wade into another expensive, bloody war to stop him - not yet. This is for Europe to deal with. Either Europe starts taking action to support countries wanting to join the EU and become part of the greater democratic world, or they need to start digging in and get ready for Putin to start pushing their borders. Of course, when/if that happens we'll be stuck wading in after a lot of damage has been done and may not have the ability to "save the day" as we did in WWII, or as England did in the Napoleonic wars.
