Well, supposing the Air Force or the Navy did bomb the Yongbyon reactor, and they got away clean without any aircraft shot down, Madeline Albright could always give the North Koreans a call and simply tell them, "We saw on the satellite overheads that your reactor appears to have had a meltdown. Seeing as how you're in compliance with the Security Council now, we're interested in sending you some aid."
Basically try and get the North Koreans to play ball.
Or, you can go the other route, which is that Kim Jong Ill goes Kim Jong Ape Shit and sends an armoured division or two over the border and into South Korea.
