In the past few days, President has gone out of his way telling the international community that he is not bluffing when he said that the military option is not off the table. Presumably, he must be concerned that the Iranians might not take him seriously enough!
In my memory of past presidents since Nixon, this is probably the first time a sitting President has to struggled so hard to maintain credibility. I venture to guess that since he was inaugurated a little over three years ago, Obama had left a litany of broken words that it is almost a given that he could be bluffing.
Some of his more memorable broken promises include not raising taxes on those making $250K or less, having the most transparent administration, no lobbyists allowed, healthcare negotiations telecasted on Cspan.
I have a funny feeling that with Iran, obama may have cried wolf one time too many!
