Light and inhale the sacred herb put upon the planet to Unite The Nations through enjoyment by the masses. Or eat some of the sacred herb and Unite The Nations. You could drink it too, or in place of, smoking or eating it.
You can try yelling at everyone to Unite The Nations but that doesn’t usually work or maybe I’ve never yelled loud enough.
Or you can try the whole, “if I have to come upstairs to Unite The Nations then all the nations are going home and I’m calling their leaders to come pick them up”, thing and see if that works.
