I do not disagree with your sentiment, I just perceive Obama's dilemma as being such that he will loose face whichever way he goes so I think he is going to pick whatever is most favorable to him according to the people he cares to impress.
Otherwise, who is going to pay him $2mil a speech or give his daughters a cushy job so his future is secure......It's like drawing a line in the sand and having Russia bail them out when it appears that not only was it crossed, but they were pissing all over your sand castle while doing it.
I'm reminded of an old asterix and obelix cartoon where in one of the scenes, asterix is in a roman tower and obelix outside and they try to go to each other pummeling the Romans along the way just to realize they switched places and have to do it again. Near the end, a roman soldier cries out, maybe if we are quiet, they won't see us or something like that.
