Here's a little different take on this subject in an article by Dick Morris:
HITLER INVADED SUDETENLAND; NOW PUTIN INVADES SOUTH OSSETIA at DickMorris.com
I'm not sure we should be getting too involved with these types of squabbles over there, but in the other hand Putin needs to know there are limits. The main thing we need to be concerned about is our missle defense system in Poland. If we should be picking our fights over there, maybe that's the one to pick instead of one about some obscure province in Georgia.
