vigilant in the region who threaten the united states and our partners and our allies. i would like to express my sincere appreciation for the professionalism of the men and women who made this operation a success. this was a true inter-agency effort so i commend our partners across the u.s. government. the individuals who plan and conduct this mission are quiet professionals focused above the mission above glory and recognition. committed people did hard and risky work and did it well. i have a few minutes to answer questions. john, over to you. >> general mckenzie, with the death of baghdadi, can you just give a sense of what the u.s. counter isis fight is going to look like? are you seeing leaders start to emerge and just as related, the troops are now moving into darasore and how are they going to supplement that counter isis mission and explain about how they're going to be protecting the oil. >> sure.
