Idk if this quite fits the bill, but hopefully it's still an issue that'd come about for nations that have compulsory vegetarianism.
Draft 1.02
Title: The War of Man and Beast
The Issue: Though mandatory vegetarianism has been adopted by the enlightened people of @@NAME@@, most of the world remains immorally omnivorous, ruffling the feathers of many a @@DEMONYM@@.
Validity: Must be vegetarian; Must not be an autarky
Option 1: "We need to beat these heartless murderers into submission," says Eleanor @@RANDOMLASTNAME@@, your slightly zealous environmental minister, invading a neighboring nation on a map with a ceramic cow. "We'll put trade sanctions on the worst offenders, and form an alliance with our vegetarian brethren, such as... um... you know, whatever we find. Now's not the time to be chicken; we have to teach these cow-murdering slaughterhouses some compassion!" She accidentally shatters the cow upon slamming it into Marche Noire.

Option 2: "Woah there, Nellie! I think you're putting the cart before the @@ANIMAL@@," farmer Old McDolan suggests, after showing your secretary a selection of no-longer-profitable pigs. "Why not promote animal rights by being a bit more symbolic? You could maybe wear a broccoli pin, or even purchase one of these here pigs and bring 'em to your meetings once in a while. Heh, maybe even dress up like a victimized farm animal, if you really want to send a message."
[effect] @@LEADER@@ has been seen wearing a chewed up rubber chicken suit
Validity: Must have internet
Option 3: "Hey, how's about we spam other nations with grotesque images and videos of animals being brutally murdered and living in rancid conditions," suggests a teenage internet troll over a video chat, showing you a brief video that you'd wish you hadn't laid eyes on. "It'd be a lot of fun, and if you'd pay me and my friends for it, we could bug everyone til the cows come home!"
[effect] the nation is a powerhouse of grotesque online material
Option 4: "Come on, son, that's hardly fair," declares United Federation CEO of Colonel Dander's Deep-Fried Pig, Colonel Dander himself, showing you a picture of a signature peppy meal. "Yer beef with animal products is not only denyin' us business in @@NAME@@, but also denyin' yer folks the savory taste of a Dandy Dander Deluxe Double-Duty Fried Pork Burger. Tell ya what. If you legalize meat eatin', I'll give ya all the free meals you want, courtesy of Colonel Dander." You swear there's a twinkle in his eye as he smiles at you.
[effect] fast food restaurants have been torched in an attempt to protect cows
