MAN, did you hit the nail on the head!!
A more full thought:
If there had been the slightest indication that Obama was a President not to be trifled with, this would not have happened. It would have made the Russians think long and hard about acting out in such a blatant manner. Instead we have a weak, pansy POTUS pretender who is probably jealous of this invasion and partition of another country.
Weakness invites violence.
