As I have read more about this situation, some things are becoming more clear. Russia claimed they were attacked first and were just preventing genocide. The comments came almost immediately and overran a huge chunk of Georgia with an estimated 2000 tanks.
I had an inkling that Georgia didn’t attack first through early news reports. After that I found an interview (speech) by the Georgian president HERE where it became more clear that Russia has been planning this for some time by a large scale military buildup on the border with Georgia. The Georgians had warned that Russia was constructing huge tank bases right over the border.
