No one knows if the agreement Donald Trump and Kim Jong Un will mean anything. If someday there is peace in Korea, that would make the world a safer, better place. Considering we were wondering if Kim was going to nuke Guam a year ago, we are seeing progress.
Trump is a dealmaker -- it's been the basis of his life. I have reservations whether Kim can be trusted and I'm guessing Trump does, too. The hard work will come later on. For peace to truly come to Korea, the North cannot continue to have an existential military force pointed across the demilitarized zone. Once even a hint of openness comes to the Hermit Kingdom, it will be almost impossible for Kim to keep control. He has to know that, too. But for this moment, it's worth noting that something we never thought we'd see has happened.
