What are the implications if Russia says "Yes, we are completely taking over Georgia?"

Question

The Russian offensive on Georgia who was the original aggressor is supposedly stopped. However, assume Russia decided to announce that they are going to completely take over Georgia. What are the implications? Would the US risk Military action and why? Would the EU risk military action? I have heard that the EU wants an alternative to Russia to obtain oil from the east.

Answer 1

The UN would place economic sanctions on Russia.

Answer 2

Same as when USA said "Yes, we are completely taking over Iraq and Afghanistan so go **** yourself because we do not answer to anyone".

Answer 3

Russia is not Iraq

I don't think that there are too many countries that would be willing to go toe-to-toe against Russia for Georgia's sake
