enemies. brett velicovich. bret, good morning to you. >> good morning. steve: when we had this terrorist strike a couple days ago in new york. this guy took the homemade pipe bombs, strapped it to himself and went into that tunnel over by the port authority and detonated it but, and so ultimately he is in the hospital because he almost, you know, got burned up pretty bad. but ultimately for a terrorist who wants to inflict damage on new york city, they could put a couple of grenades on a drone and they wouldn't even get hurt. blast radius. the fact is isis has proven this is effective tool on the battlefield. it's been nearly two years since we saw the first commercial use of a drone in iraq where isis fighters took explosives, strapped them to a drone and dropped them over coalition forces.
