Can you imagine if they started flexing their muscle with other countries closer to the EU?
Who "they"? Georgians? Unlikely... cause they're the US tool and they don't wanna use it against any ally-country. Russia is obvious geostrategical opponent of the US, it's not a secret. We (I mean "people") are welcome to choose either to support the truth or your own interests.
Russians? I don't really know... :) If somebody else durst annihilate 2000 of its citizens and friends per night, I guess they would respond.
With only 10 missiles what's Russia really worried about??
I assure you as a "profy" (heh... not modest of me:)) in that kind of missiles that there're lots of reasons to worry about. The basic threat is not the missiles itself but their navigation system on the ground that's able to track our missiles on the beginning stage of their flight.
