Russia has responded with a massive show of military might and could go so far as to overthrow the Georgian president, who is seen as pro-US and therefore a threat on Russia's southern border.
The US has responded to this by accusing Moscow of "resisting peace and wanting regime change."
Ponder those words by a George Bush-led administration.
This bitter little war is one of the unforeseen consequences of the Iraqi invasion back in 2003, which became an explicit "regime change" war after the lie over Weapons of Mass Destruction was exposed. Powerful states around the world now see they have the explicit right to invade and "regime change" any neighbour without the threat or sanction of international retaliation.
