I don't know. Maybe all of it is an improvisation.
Anyway, if possible, they will prefer non-military and "half-military" means.
At the moment, it does look like one of the cards being played.I think there is about 1 / 10 chance that all hell breaks lose in Ukraine and Russia ends up doing some kind of "peacekeeping" intervention
I don't know about that but I believe the rest of the Ukraine is no lesser prise.NATO must have had some VERY grand plans for Crimea, considering how pissed off they were at having it snatched from right under their nose. I bet they were planning the mother of all foreign US bases right there in Sevastopol!
