There's only one strategy that will work in NK:
Trump just needs to neutralize NK air defenses so that containerized McDonalds restaurants can be dropped all over the country and rolled over the border from China. The people, including the military, would come storming into the streets to eat for the first time in their lives (that wasn't rice and fido) and the crisis would be over. Soldiers would gladly drop their rifles to pick up a #1 value meal, with up-sized fries and a coke. The biggest risk would be running out of potatoes or Big Mac sauce. In a month they'll all be fat and sassy and will have a new, less clownish, icon to adore in Ronald McDonald.
