Only one can say 'yes' and we know he didn't from the simple fact that there wasn't any rescue attempt. He might have said 'no' but he didn't have to. All he had to do was remain silent. He did one or the other.
Well .. my Navy Seal told me NO ONE BUT OBAMA CAN GIVE THE ORDER TO SEND PEOPLE INTO ANOTHER COUNTRY UNDER THE CBA EXCEPT OBAMA.
Not even the SecDef. All the SecDef or Ham could do was ready any troops (which was done) - but neither of them HAS THE POWER TO ORDER THE MILITARY INTO ANOTHER COUNTRY.
End of story!!!
