On July 29, 2008 South Ossetia said two South Ossetian villages had been fired on by Georgian forces in response to South Ossetia reinforcing its positions on the perimeter of the conflict zone

As we can see, Georgia has been firing on South Ossetians even in the absence of any attacks coming from South Ossetians. Georgia's bombing and invasion of South Ossetia had notthing whatever to do with any skirmishes instigated by South Ossetians or anyone else. Georgia bombed and invaded South Ossetia for no other reason than because it wants to force South Ossetia to be reabsorbed back into Georgia. And any and all violence by South Ossetians has been in response to these efforts by Georgia. This makes Georgia the aggressor.
