Expect the Trump Administration to quote this report extensively, especially the section which states:

"The implementation of existing sanctions lags far behind what is necessary to achieve the goal of having NK abandon all weapons of mass destruction."

If military action is taken to decapitate the NK regime, part of the rationale will be that the UN documented the failure of sanctions and diplomacy to contain NK's WMD program.

The US probably would not ask for a UN resolution for military action right now because the request would be vetoed by Russia and China.
