the speech. some things i wondered if they were simply political. at one point he's talking about the timeline in afghanistan. he says and next july we will begin a transition to afghan responsibility. he goes on later to say, but make no mistake this transition will begin because open-ended war serves near our interest nor the afghan people. of course that's popular with much of his base electing him. i guess to throw into the mix let me give you some sound of what general conway has said about the idea of talking about timelines. >> probably giving our enemy us is . he may be saying in fact we've intercepted communications that say we only have to hold out for so long. >> greta: why put into this speech tonight even if he intends to meet that timeline why make that public announcement? >> i think you put your finger on it. there was a base element.
