"I believe Eastern Ukraine has invited putin to come in and annex them"

I think Eastern Ukraine is a given, driving south through Odessa (nearly as Russian as Moscow) and into Transwhatever.

There'll be much finger wagging over it.

But a move into the Baltics would trigger war.

According to some of the Ukrainians, Kherson is a key to Crimea over the long haul (unless Putin builds a bridge across to Kerch), and Kherson also lies on the path (more or less) to Odesa. Kherson is not very Russian (25%, I believe I saw on one map), so that's where things could get sticky. http://www.angelfire.com/extreme4/kiddofspeed/maydan/map.gif
