Bad answer, bb... We ain't talkin' shots fired in return for shots fired 10 or 20 years ago but shots fired during the "latest" skimish... Seems that crredible sources have those shots being fired by the Georginas...
If the Russians had fired them then, yeah, Georgia would have been legally permitted to defend itself... But doesn't look as if that was the case...
Might of fact, with all the John McCain bluster and his own staff memeber a lobbiest for the Georgian governemnt it is questionable if Georgia would have been so brazen to do what it did... It was stupid on their part... Very stupid...
