Thank you for your question, sir. It's good to see you again as well.
There are various stages in a ballistic missile engagement. The first stage is the intelligence and warning, or the indicators and warning. When a cycle of provocation is initiated, at the onset I may or may not be in the room for those discussions if it will involve ballistic missile defence. It's very much dependent on how the theatre in charge of North Korea, the Pacific command, decides to disseminate the information as releasable to its allies or as U.S.-only information.
Once a missile is launched, the missile warning mission is done by NORAD. The missile is launched and we have infrared signature from that missile. NORAD processes that missile. I'm fully involved and the NORAD personnel are fully involved. Once it gets into outer space and the object is cold and can be engaged by ballistic missile defence, we will not leave the room. We will still be involved by virtue of doing the missile warning, but we have no voice in the deliberations, the tactics, or on the decision cycle to engage or not engage that missile. USNORTHCOM does that engagement.
Once the engagement is done, if it passes.... The only way to figure out if it's a success or a failure is in the detection. If there is no re-entry of these objects detected, then it's probably a success. If there's a re-entry, it's for NORAD to characterize all re-entries back into the atmosphere, and then the NORAD chain of command is involved again. If it's armed with a nuclear weapon, NORAD again is in charge of disseminating and processing nuclear detonation worldwide. There is a change in the chain, in what we call the kill chain of that ballistic missile, between NORAD, USNORTHCOM, and back to NORAD.
