Why do Democrats have to offer suggestions? During the campaign Trump promised he was going to solve the problem of North Korea.

Trump repeatedly hammered  Hillary Clinton on her failure to curtail  North Korea  when she was the secretary of state. His campaign created a lengthy list of ways in which Clinton had failed, citing news reports of successful nuclear tests and rocket launches.

 When North Korea said that it might soon test an intercontinental ballistic missile, he declared bluntly, “It won’t happen!”

Once he became president, though, Trump’s tone shifted, “It's not as simple as people would think.”

So he has no plan to deal with NK, just like he had no plan to repeal and replace Obamacare on Day One, saying “nobody knew that health care could be so complicated”.  Everyone knew it except him.

Eight months into his administration there is no boarder wall, no infrastructure bill, and no tax reform. The man who said, "I alone can fix it," hasn't fixed anything.
