Herbert E. Meyer offers this situation as a metaphor, to contemplate when considering what we should be doing about Iran:
To think clearly about the looming crisis with Iran, close your eyes and imagine that you’re standing outside your children’s school. It’s 2:55pm, and you’re chatting amiably with other parents while waiting for the 3pm bell to ring. Suddenly you see a man running toward the school, holding a hand grenade and shouting: “I hate kids. I welcome death.”
Now, what do you propose to do?
