If you don't give me all your money, I'm going to set off this nuclear device
There was a lot of anxiety about nuclear war and nuclear winter and the possibility that someone, maybe Ronald Reagan, was going to hold us all hostage with the US nuclear arsenal back in the 1980's, when Devin drew this cartoon. Devin's terrorist here might have a legitimate nuclear device, or it might be a part that he stole from a car wash. It doesn't seem to be much of a threat, but the background images, nameless shapes of nations, garbage cans, a strange large ventilation device, all see fairly threatening. But the person in the comic with hands in his pockets, still doesn't seem all that frightened. He's already see it all. Or maybe he's reaching his hands in his pockets to pull out that money.
