Perhaps, perhaps not. But it is worth the risk of waiting, so long as we don't let our guard down.
We must continue in readiness for a North Korean attack. Frankly, I think NK WILL die a quiet death for the simple reason that the guys who will be in charge of carrying out the last-minute orders will be far more concerned about not being tried for war crimes by the new, United Korea that will emerge after NK's collapse. This goes double for anybody involved with nukes. Once ultimate collapse is obviously in progress, orders simply will no longer be obeyed at all.
