The speculation that Russia could bomb Georgia shortly after the visit of Barack Obama seems to suggest a whole new definition of what it means to hit the "reset button."  I don't think it will happen.  From Associated Press:

Former Kremlin adviser Andrei Illarionov predicted that if Russia were to take military action against Georgia, it would take place directly after Obama's visit and that Moscow would portray its decision as having been made with Washington's approval. He also said Russia doesn't want to occupy Georgia.

"The main goal is to turn Georgia into something like porridge, from a political, military and ethnic point of view," he said.

"Most important is the destruction of the political stability of Georgia," he told reporters.
