Is Obama going to do anything? If not he risks appearing weak to the enemies of the US and it will only encourage Iran and North Korea to accelerate their efforts in developing nuclear weapons. Perhaps Obama will avoid war at all costs for fear of losing the virtual Nobel Peace prize that he was awarded a couple of years ago? But it is not good if you talk tough and then fail to follow up with actions when the "red line is crossed". Is he too nice a guy to be US President? Or will he step up to the plate now that there is no other alternative?
