Special interest affiliates were watching intently and taking notes. There is always more than meets the eye when a President interrupts Americans watching their beloved sports to share a speech that many reporters commented wasn't anything different. Some journalists in California were visibly angry about having to be present for work to report on an address that didn't move them much or wasn't very newsworthy.
In my opinion, the President looked worn out, not very convinced or confident of what he was reading, talking as if he was calming a few people in his personal social circle down who might have been venting to him about the shootings and other things, and overall appeared ready to go smoke a cigarette.
The change of words from Isis to Isil was more of that word play that goes on when something is about to go down or a new script is being developed for the incoming president. The reassurance that all will be handled and the examples of what has already been done was to tickle the ignorant listeners' ears. Meanwhile, those in the know aren't the least bit concerned about the rhetoric because along with every tragedy more distractions are created for a set period of time while pawns in the games (around the world) redirect focus and realign their positions overseas and on American soil. The plot is thickening and you might as well be prepared for more war and rumors of war.
