we're being joined by colonel cedrick leighton, former member of joint chiefs of staff. colonel, welcome to you. you have been following coverage, listening to discussion. first, what do you make of this tragic news, and does it change the priorities here? does it change the strategy? >> well, randi, i think it's obviously a horrible and tragic event. as we have been discussing here. the key thing is that it will not only accelerate i think in the u.s. and i believe also u.k. response to everything that is going on, but it will also galvanize movements within the pentagon and the u.s. government, especially the white house, to alter the strategy, to make the strategy a much more direct strategy and much more kinetic strategy, i think, than they had originally planned on doing. of i think the gradual approach that the administration has outlined, i would think is -- in essence, not meeting the needs of the moment. and in this particular case, you've got the islamic state, isis, going in and killing all of the hostages they've got. they're basically going down their list.
