Trump is an idiot, and hopefully, he'll just accept that he's an idiot and do the best thing at this point.

Trump left ZERO middle ground for North Korea.

So, it would seem, it is left to North Korea to choose between what it apparently believes will be an inevitable invasion by the US of a non-nuclear NK, or being starved to death.

I think NK chooses to starve to death, while finding nourishment wherever it can along the way.

I think Trump has put himself into a box, and that his ego will not permit an NK with nuclear weapons, or a negotiation process that permits NK to keep its nuclear weapons, because, simply, if not he will look like an idiot to his "base".

But, I have to hope he'll overcome that, go to the table, and take military confrontation off the table.

Otherwise, at some point, Jong Un presses his buttons (maybe his last act before starving to death).  Then, millions die.

I actually think Trump has lost us South Korea as a functional ally, and moved US back to Japan.
