So, I take it that Russia moved in “non-peacekeepers” and that triggered Georgia’s attack?
Georgia is not innocent here. Tensions have been high in the region long before Georgia was ever formed. On August 7th Georgia attacked with armor and artillery killing sleeping South Ossetian civilians. Their peacekeepers also turned on and killed Russian and South Ossetian peacekeepers. It was a horribly stupid move on their part.
Here is some background on South Ossetia:

And some less biased prewar (2006) info:

Just because we are the US, and Russia is Russia, does not make Georgia any less stupid or reckless.
