After watching Assad kill so many hundreds of thousands and exile more hundreds of thousands of his own people, he is my choice as murderer-in-chief.

He was either incompetent or a liar when he and Putin said that they turned over all his chemical warfare stocks for destruction to Obama. 

Obama and Kerry were either incompetent or disingenuous.  

Obama,  the wordsmith, said that all "declared" stocks had been destroyed.

The weasel word "declared" is what makes him disingenuous.   

Kerry actually said "all stocks" sometimes and "all declared stocks" at other times.
