If he had any knowledge, good will, understanding of diplomacy or understanding of reality, period, he would comprehend that North Korea is now so desperately poor that it’s leader would gladly back off from nuclear provocation in exchange for aid or at least relief.
Trump, however, is frantic to change the subject from RussiaGate.
He’s also saddled with the demented whisperings of Steve Bannon, whose apocalypse-orgasm-meter is set to detonate.
Trump has no gauge on empirical reality, so he cannot visualize what the endgame of nuclear confrontation would be.
At least Trump’s shrill, nasal, saber-rattling sounds so tin pot and ridiculous that cooler heads may encourage all concerned to laugh the whole thing off.
