Yes. I doubt it will ever happen from US part, unless otherwise N.Korea is mad enough to provoke a war by hitting some US target. The only real weakness the US has here is that a war with N.Korea risks the lives of their allies. South Korea and Japan are directly under the threat so millions of civilian lives are at stake. So the international pressure always placed on the US not to go for a war. NK knows that and they take advantage of it to develop their missile and nuclear program. China btw playing behind the scenes to achieve their strategic goal out of this. That is to make US leave that region. Thats what both NK and China wants and also the Russia. But I am afraid that won't happen. I am not against NK becoming a nuclear nation if they believe that is needed for their country's safety. But it has to be with responsible hands. Not with someone like Kim.
