this world is becoming scarier and scarier each day..

Even with common perception that Russia is an evil side, which is probably true, Georgia launched the airstrike first. It just gives Russian troops a red carpet to get in. Unless we know nothing on the real course of events, that was indeed a stupid step, giving Russia all possible excuses.
BTW, Georgian government is getting a significant financial aid from USA. Why did not they consult with their close allies, before opening military actions? Or, they did and got OK from USA?

I'd say the US aren't listening to Russia.
Do you believe that if the US forces weren't spend to thin the then they would be able to take Russia on? Besides Russia responded to the Georgian attack on South Ossetia not invaded Georgia
