Yesterday, the suicide bombings of Shi'ite mosques in Yemen resulted in the deaths of 137 people, for which ISIS proudly took credit. If you are wondering why (Sunni) ISIS would want to bomb mosques were Shia worship, it all goes back to the death of the Prophet Mohammad and a disagreement over who his rightful successor should have been. Of course, it had nothing to do with Islam (yesterdays' bombings).
It also brought to light President Obama's mentioning Yemen as one of his administration's "successes". As I write this, it has just been announced that we are pulling all remaining special military forces out of Yemen. That follows the evacuation of our embassy.
