No, it isn't. That's crazy talk. War very much is "I have a larger army so I win", when all other aspects are equal - and they are. The idea that George could ever repulse a Russian attack is as insane as proposing as Georgia could repulse an American attack. The difference in numbers and sheer scope of weaponry arrayed against Georgia renders it impossible.
You can't think your way out of being overwhelmingly outnumbered and facing invasions from two different directions from the same enemy simultaneously.
