President putin has said on more than one occasion that the fall of the Soviet Union was one of the biggest tragedies in history. there seems to be little doubt that he would like to reverse that and rewrite history. he has already made moves in georgia and moldova. Should those moves go unchallenged by the west, especially the united states then would could be moving toward some ultimate conflict that would make wwii seem like a marble game. there are no easy solutions, but something must be done. When president kennedy came into office his first challenge was the bay of pigs failure---the russians perceived weakness and that led to the installation of missiles in cuba and to the cuban missile crisis where kennedy finally found his backbone and stood up to the russians. The point here is that if kennedy had not shown weakness in the beginning of his presidency we might have not been pushed to the brink of wwiii during the missile crisis. putin sees obama's weakness and will not cease his aggressive acts until obama grows a set.
