this was a scenario where there were direct threats from isis-k against our troops who were on the ground in afghanistan. that was the scenario where the strike was made. it was done in error. obviously there was a horrific tragedy that happened. i won't predict what the impact will be. >> on august 26th in afghanistan. the president said i ordered commanders to develop plans to strike isis-k. we are respond with force in the moment of our choosing. should we still be anticipating there will be a military response to what happened there in kabul? >> against, isis-k? yes. it's important. this is a good question that has been asked. others asked me this. there is a difference between a self-defense strike based on imminent threat to u.s. forces. these were threats as you lived
