But then the PETA letter takes a hard turn into some curious shadows, continuing, “And because eating vegan has been shown to help curb violence.” The group doubled down on that in an accompanying press statement this week, writing, “Eating vegan meals has been shown to help curb aggression.”

As in, people-on-people aggression? Apart from arguably aggressive acts of procurement, eating cheese or fish makes a person more aggressive?

A fascinating idea and, if true, a worthwhile consideration. The justification for the claim, according to PETA’s letter, was: “At Alabama’s highest-security prison, for example, prison operators found that serving inmates vegetarian meals as part of a violence-reduction program resulted in a significant decrease in behavioral problems … We’re pointing out this link in our call to Kim Jong Un to change his diet, which might just lead to a change of heart in his dealings with other nations. You never know!”

Do we never know? If it is presently difficult to get Kim Jong Un not to repeatedly violate international accords and human rights in his own country, why would it even be conceivably possible to assume he will change his own diet at the suggestion of Rex Tillerson?
