I mentioned earlier in the thread that Moldova is next due to having Russian speaking seperatists similar to situation in Ukraine. Moldova was also part of the old USSR and would make a great buffer zone from nato nation like Romania. Only way this can stop is if Moldova unify with their cousins in Romania which the thought has been flirted with between the two nations.
I think the talk of "Moldova is next" is a stretch. They have no interest in Moldova, sure they want them to be friendly, but not to take over.
