“Georgia didn’t attack South Ossetia until Russia was already in it, right???”
Actually Russian peacekeepers have been there since 1992 when they and Georgia signed a pact stating that Georgia would never use military force to retake the region.
So, I take it that Russia moved in “non-peacekeepers” and that triggered Georgia’s attack?
Actually you skipped the insignificant detail about how the Russian "peacekeepers" and Ossetians were shelling into Georgia.
