The Georgian military had no chance of defeating the Russian invasion, but at least they could have put up some defense at Gori. At the very least they could use hit and run tactics and insurgent responses to the invasion. Instead, they fall back without firing a shot. They have 200 T 72's, so where are they? They don't seem to defend anything with much zeal. If that were Detroit, I guarantee the Russians would be fighting there for weeks if not longer.
The Georgians really don't seem as if they are willing to really defend their country. And, maybe it isn't worth defending in their view? 14 years ago most of their officers were Soviet officers and that must make it difficult to decide to fight the Russian military.
