Now the Obama administration appears to be waiting it out. Though it no longer favours the term "strategic patience" - mocked as "patience, without a strategy" - its actual approach appears unchanged. It does not regard Pyongyang as a priority, and is not sure what to do about it.
It would take a courageous president to restart talks with Pyongyang. The Iran nuclear deal was extremely difficult and highly controversial; a North Korea deal would be more so.
No one wants to reward bad behaviour; at best the outcome would be a cap on development.
But doing nothing is not the same as maintaining the status quo. Pyongyang will continue its race to gain weapons - and redouble its efforts if ignored.
Engagement is not an attractive option; but the US should choose it, and soon.
