Once again over the weekend, North Korea tested another missile, and once again, it was a humiliating failure that went straight into the sea. Unless Kim Jong-Un is trying to start a war with Aquaman, that’s probably not what he was shooting for. Naturally, President Trump was standing ready on Twitter to respond to the missile flop with some world class trolling.

It’s easy to mock the wide gap between Kim’s grandiose threats and boasts and his failure to launch even a small missile. But it’s a threat that has to be taken seriously. If North Korea keeps defying the world by test-firing missiles, eventually, they're going to figure out how to hit something other than Charlie the Tuna. If you let a child play with fireworks long enough, someone’s going to get hurt.
