What to do if you happen by a university peace rally in order to teach naive college students who have not experienced war in their lifetime why force is sometimes needed :

  1. Approach naive young student chanting about "peace" and saying there should be, "no retaliation."
  2. Engage in brief conversation, ask if they think military force is appropriate in response to attack killing over 6,000 people.
  3. When he says "No," ask, "Why not?"
  4. Wait until he says something to the effect of, "Because that would just cause more innocent deaths, which would be awful and we should not cause more violence."
  5. When he's in mid sentence, punch him in the face as hard as you can.
  6. When he gets back up to punch you, point out that it would be a mistake and contrary to his values to strike you, because that would, "be awful and he should not cause more violence."
  7. Wait until he agrees with you that since he has pledged not to commit additional violence it would not be right for him to strike you back.
  8. Punch him in the face again, harder this time.
  9. Repeat steps 5 through 8 until they understand that sometimes it is necessary to punch back.
