I can assure you that we look at the depth of the tool bag and assess what's possible all the way up, short of the kinetic response of the missile or gun employment. We're always trying to minimize the collateral damage, not only from the use of the weapon but also because of the follow-on impact of potential debris on the ground. That's part of our element.
We look in the tool bag. That may include non-kinetic capability. In this event, the best tool available to NORAD at the time was the use of fighters and of the specific AIM-9X missile.
We're not stopping short. We are going to continue to look at what else is required to carry out the mission.
