Couple of things to realize. One, the Orange Piss Pot is claiming credit for this. Which is....apt. Two, this might fall apart like every other time they've tried to end the war. Three, North Korea's main nuclear reactor just melted down so they don't have the materials to make any more nukes. Four, Russia is trying to get an oil pipeline down through the peninsula and Trump's fixation on North Korea has never been in Putin's plan. So bear all that in mind.
Ironbite-on the other hand, if this does end the war, Trump won't have the excuse to attack North Korea without going through Congress.
