It shows that, at least up to now, the DPRK has not been able to leverage Trump's domestic troubles to get a deal to its best advantage.

I do agree with your assessment of the Warmbier affair, though. You don't have to be an inscrutable Asian to realize America has lost face on this issue. A public statement by Kim, reiterating what Trump now alleges, would have cost the N Koreans nothing but would have gone a long way towards establishing an atmosphere of trust between the two countries. The fact they have not done so speaks volumes amongst the undecided and uncommitted.

As it is, we have yet another example of Trump baring his rump and assuming the position to yet another vicious dictator. N Korea, Saudi Arabia, Russia, Turkey, the Philippines....Trump may be perceived by the drooling cretins on the American Right as a tough guy, but in the rest of the world he's coming across as the stereotypical girly man. Not only does this encourage the bad guys, it scares those allies which have counted on us in the past for support.

Ask any Kurd. You'll get an earful.
