if Abkhazia doesn't want to be a part of Georgia, so they won't, but Georgia want, so they have to take it by army, by war.
hmm, South Osetiya is almost all populated by russians, by your logic, it must be part of Russia, and this is one more reason why russian army was there...
they can't take Ukraine, Ukraine depends on Russia for a little, but they need in powerfull 'friend' who's very influence in the world, and USA took Georgia as 'pawn'...
