Incredible news. Connecting a few dots, I hope that with the recent announcement that Americans should leave Syria, that something is really being done to cut off the major funding and organization at the head.
And also agree, smart move on the quick burial at sea, for the reasons stated above. If he was kept alive, there could have been many attempts to kidnap and trade, threats to others to get him freed, etc. (even if the chance of us freeing him was nil, they would have a ton of ambition to try). This limits the options, and while there will certainly be reprisals, they will hopefully be short-lived, amateur, and well-thwarted.
Even though I'm not a big Obama fan (or of any politicians recently, really), hats off to him and the people he has working this, as well as the intelligence and Seals and others who have been doing this all along. VERY well done IMO, and it makes me very happy and proud.
